903.3 Ground-Mounted Sign Supports
Signs are ground-mounted whenever possible unless mounting overhead is justified. All ground-mounted structural and sheet signs are mounted on pipe posts, wide flange (WF) fabricated steel posts, u-channel posts, perforated square steel tube posts or wood posts as shown in the standard plans.
Cross-sections of relocated or new signs are drawn and included in the final plans. The cross-sections are drawn to a 1" = 5' (1:50) scale to allow for scaling of quantities. The following information is shown for each sign: sign number, station, edge of travelway, edge of shoulder, sign dimensions, guardrail and curb locations, post configuration, all non-standard horizontal and vertical clearances, backing bars and post lengths. Random grid lines are used to draw the cross-section and elevations are not shown. For multiple post designs, number the posts from left to right, and use only one post design type per sign. All cross-sections are drawn as the driver views the sign face. Existing signs relocated to new posts and posts being used in place are shown with dashed lines. All back-to-back signs are noted, and the far sign is shown with dashed lines. It is not necessary to outline the foundation size since this information is noted in the standard plans. A note is added to the cross-section if the foundation depth is greater than the minimum shown in the standard plans. See Standard Plan 903.03 for recommended foundation depths for various post designs and slopes. The post stub length is shown below the finished ground line in order to scale the correct post pay length. Acceptable examples of ground-mounted cross-sections are available.

Whenever possible, available overhead sign support structure columns, signal poles, etc. are used to mount sheet signs. This is less expensive and encourages cross comparisons of signal and signing plans. Utility poles are not used to mount signs.
903.2.1 Horizontal Clearances (MUTCD Section 2A.19)
Standard. For overhead sign supports, the minimum lateral offset from the edge of the shoulder (or, if no shoulder exists, from the edge of pavement) to the near edge of overhead sign supports (cantilever or sign bridges) shall be 6 ft. Overhead sign supports shall have a barrier or crash cushion to shield them if they are within the clear zone.
Ground-mounted sign supports shall be breakaway, yielding, or shielded with a longitudinal barrier or crash cushion if within the clear zone.
Guidance. For ground-mounted signs, the minimum lateral offset should be 12 ft. from the edge of the travelway. If an existing shoulder is wider than 6 ft., the minimum lateral offset for ground-mounted signs should be 6 ft. from the edge of the shoulder or front face of curb.
Where existing signs are located within 6 ft. of a utility pole, they should be relocated to provide a minimum distance of 12 ft. where practical through normal sign replacement.
EXIT signs placed in the gore only require a 2 ft. horizontal clearance from both edges of shoulder or front face of curbs.
For divisional and channelizing islands, a 2 ft. offset should be maintained between the edge of sign and the front face of curb. For islands with restricted width the sign should not extend beyond the curb. When signing at the nose of a 4 ft. median, a 1 ft. offset is acceptable between the edge of sign and the front face of curb.
Maximum clearances will depend on roadway geometrics, profiles, and cross-sections, which all affect the visibility of the sign. Sheet type and structural type signs are generally to be placed no more than 15 ft. from the edge of shoulder.
New sign installations should be a minimum distance of 12 ft. from existing utility poles.
Support. The minimum lateral offset is intended to keep trucks and cars that use the shoulders from striking the signs or supports.
It is acceptable to adjust the standard horizontal clearance to obtain a better cross-section and still maintain sign effectiveness and visibility. For example, signposts are not placed in the center of ditches; therefore the horizontal clearance may be adjusted to better span a flat bottom ditch. Existing drainage structures, pull boxes and sidewalks may also affect horizontal clearance.
A minimum sight distance of signs should be maintained. There should be a minimum of 60 ft. of sight distance for each inch of letter height with a 1,000 ft. minimum for all mainline signs. A minimum of 250 ft. of sight distance is desired for signs on conventional roads, refer to Tables 903.6.3 and 903.6.7. When this is not possible, relocating the sign or providing additional advance signing should be considered.
Horizontal clearances are not noted on Form D-29 unless they differ from the standard 6 ft. offset.
Guidance. All supports should be located as far as practical from the edge of the shoulder. Exposing traffic to sign supports should be minimized by placing signs in such locations as behind existing roadside barriers or on over-crossing structures.
A minimum sight distance of signs should be maintained. There should be a minimum of 60 ft. of sight distance for each inch of letter height with a 1000 ft. minimum for all mainline signs. Signs on conventional roads should have a minimum 250 ft. sight distance. Refer to Tables 903.6.3 and 903.6.7. When this is not possible, relocating or providing additional advance signing should be considered.
Option. Where permitted, signs may be placed on existing supports used for other purposes, such as highway traffic signal supports.
Standard. If signs are placed on existing supports, they shall meet other placement criteria contained in this manual.
Option. Lesser lateral offsets may be used on connecting roadways or ramps at interchanges, but not less than 6 ft. from the edge of the travelway. In urban areas where lateral offsets are limited, a minimum lateral offset of 2 ft. may be used. A minimum offset of 1 ft. from the face of the curb may be used in urban areas where sidewalk width is limited or where existing poles are close to the curb.
Support. Figures 903.1.23.1 and 903.1.23.2 illustrate some examples of the lateral offset requirements contained in this portion of the article.
It is acceptable to adjust the standard horizontal clearance to obtain a better cross-section and still maintain sign effectiveness and visibility. For example, signposts are not placed in the center of ditches, therefore the horizontal clearance may be adjusted to better span a flat bottom ditch. Existing drainage structures, pull boxes and sidewalks may also affect horizontal clearance.
903.2.2 Vertical Clearances (MUTCD Section 2A.18)
Standard. Vertical clearances for single wide-flange and all post designs are set from the edge of travelway to the bottom of the lowest sign. Vertical clearances for multiple wide-flange posts are set from the edge of travelway to the bottom of the lowest sign, or the length of the shortest post, whichever requirement provides the higher clearance. Vertical clearances for different designs are shown in the standard plans.
Supports for SH signs, such as regulatory, warning and route shield markers, are designed to provide a vertical clearance of 7 ft. 0 in.
All two- and three-post signs (any LOGO sign or sign with white legend on green, blue or brown sheeting) have a minimum 7 ft. 6 in. clearance from the edge of travelway. Also, the shortest post is a minimum of 7 ft. 9 in. above the ground line to the bottom of the lowest sign. This will provide sufficient post length to allow hinge plate installation, provide a 7 ft. 0 in. clearance for errant vehicle impacts, and a 6 in. field adjustment.
Due to wide-flange post limitations, large vertical clearances of 25 ft. or more are avoided by either moving the sign or considering a truss-mounted sign.
All two- and three-wide flange post signs contain hinge plates as shown in the standard plans. On the shortest post a vertical clearance of 7 ft. 9 in. is maintained from ground line to the bottom of the lowest sign. This will allow sufficient length of post for a hinge point cut line 3 in. from the bottom of the lowest sign. Maintaining this clearance on the shortest post is critical for exit gore and other signs located between roadways and have high exposure to traffic.
Option. The height to the bottom of a secondary sign mounted below another sign may be 1 ft. less than the height specified above.
Where signs are placed 30 ft. or more from the edge of the travelway, the height to the bottom of such signs may be 5 ft. above the level of the pavement edge with a 5 ft. minimum post length.
A route sign assembly consisting of a route sign and auxiliary signs (see Route Sign Assemblies) may be treated as a single sign for the purposes of this article.
All posts except structural posts should have a minimum clearance of 5 ft. above the driving surface with a minimum post length of 5 ft. above the ground. The mounting height may be adjusted when supports are located near the edge of the right of way on a steep backslope.
Support. Without this flexibility regarding steep backslopes, a decision to relocate the sign closer to the road could be made, which might be less desirable.
903.2.3 Pipe Posts
Steel pipe posts are used for sheet (SH) signs up to 30 ft2. Available pipe size inside diameters are 2-1/2 in., 3 in. and 4 in. Post sizes are determined using the Signpost Selection Guide. A printable Signpost Selection Guide for use in the field is also available. It is recommended to provide a two-post design for sheet sign widths greater than 3 ft. 6 in. (other than diamonds or the 48 in. and 60 in. Yield). The extreme width sign, W, is calculated as: W = (area of signs + area of exposed backing bars + area of post above bottom of sign)/(extreme height of sign). For additional information, consult the Signpost Selection Guide (signpost calculator).
It is desirable to keep posts out of the ditch flow line, when possible.
Breakaway assemblies are required on all pipe posts, regardless of location. Multi-direction assemblies are also required and are noted on Form D-29.
The standard plans show design data for computing the weights (masses) of pipe posts, along with data for computing footing quantities.
903.2.4 Wide Flange (WF) Posts
WF posts are used for mounting signs larger than 30 ft2. The post design number is determined from Signpost Selection Guide when a sign is mounted alone or with an exit panel above the main sign. A printable Signpost Selection Guide for use in the field is also available. The extreme width sign, W, is calculated as: W = (area of signs + area of exposed backing bars + area of post above bottom of sign)/(extreme height of sign).
For post designs Nos. 3, 4, 5 and 6 having weights greater than 18 lbs/ft., posts shall be spaced at least 7 ft. apart. For post designs Nos. 1 and 2, posts may be spaced less than 7 ft. apart. Do not use three No. 1 or 2 posts with a sign width of less than 10 ft. 6 in.
In many cases, two designs are possible using a two- or three-post design chart. There are no special criteria for determining which of these two designs to use. Generally, signs from 6 to 17 ft. wide will be designed for two posts, while signs wider than 17 ft. requires three posts. It is desirable to keep posts out of the ditch flow line and median, when possible. This may be a deciding factor for a two- or three-post design.
While pipe posts are cheaper, a single WF post can support side-by-side route marker assemblies. Normally a number one WF post design will support a side-by-side assembly. For larger two-post sign design combinations consult the Signpost Selection Guide. The next higher post design is used when in doubt.
Standard Plan 903.03 shows data needed for computing the weights (masses) of WF posts, along with data to compute footing quantities.
Breakaway assemblies are required on all WF posts, regardless of location and are noted on Form D-29 (see Figure 8-03.4). Multi-direction assemblies are not available for WF footings.
903.2.5 U-Channel Posts
These supports are galvanized 3 lb. (1.4 kg) steel posts used primarily for installing SH signs. Details of these posts are shown on Standard Plan 903.03. The number of posts to be used is based on the sign area for each installation and is calculated from the Post Size Requirements Table in Standard Plan 616.10. The Signpost Selection Guide is also available. Use of these posts should be based on discussions with district Traffic. These posts are paid for by the linear foot. No additional payment will be made for hardware.
903.2.6 Wood Posts
These supports are pressure treated 4 in. x 4 in., 4 in. x 6 in. or 6 in. x 6 in. wood posts used primarily for installing SH signs. Details of these posts are shown on Standard Plan 903.03. The number of posts to be used is based on the sign area for each installation and is calculated from the Post Size Requirements Table in Standard Plan 616.10. Use of the Signpost Selection Guide is available as is a printable Signpost Selection Guide for use in the field. Use of these posts should be based on discussions with district Traffic. These posts are paid for by the linear foot. No additional payment is made for slotting the larger posts or for hardware.
903.2.7 Perforated Square Steel Tube Posts
These supports are galvanized 2 in. square 12 gauge steel posts used primarily for installing SH signs. Details of these posts are shown on Standard Plan 903.03. The number of posts to be used is based on the sign area for each installation and is calculated from the Post Size Requirements Table on Standard Plan 616.10. Use of the Signpost Selection Guide is available as is a printable Signpost Selection Guide for use in the field. Use of these posts should be based on discussions with district Traffic. The actual posts are paid for by the linear foot. An additional bid item must be included for the anchor sleeve, paid for by the linear foot, for each post used. No additional payment will be made for hardware.
903.2.8 Secondary Sign Supports
These supports are aluminum wide-flange posts used to attach service signs and exit number panels to structural signs. Details of these posts are shown in the standard plans. There is no direct bid for these posts.
903.2.9 Backing Bars
Backing bars support wide SH signs and side-by-side route assemblies. The standard plans show requirements for backing bars and additional information is given in 903.18.3.8. Lengths and the weight per foot of backing bars are shown in the standard plans. Backing bars are totaled and included in the bid item for structural steel posts. Backing bars are totaled on Form D-29.
903.2.10 Hinge Plates
Hinge plates are installed on all multiple post WF post designs as shown in the standard plans. Hinge plate cut lines are 3 in. below the bottom of the lowest sign. The cut line is a minimum of 7 ft. 6 in. above the ground line on the shortest post. No direct pay is made for hinge plates.
903.2.11 Breakaway Assemblies
Breakaway assemblies are provided for all ground mounted pipe post and WF post designs regardless of location. Breakaway assembly details are shown in the standard plans and additional information is given for preparation of sign plans at 903.18.3.7and at 903.14.1 for sign support information. Breakaway assemblies are totaled on Form D-29.
Breakaway assemblies are not required for U-channel or wood posts. For perforated square steel tube posts, though, a breakaway design may or may not be required depending on the configuration of the posts. The Signpost Selection Guide should be referenced to make an appropriate determination.
903.2.12 Orientation (MUTCD Section 2A.20)
Support. The brightness of the sign may drop 24 percent when the normal offset from edge of travelway is increased to 30 ft. The legibility remains at an 80 percent level or higher when using the standard 6 ft. offset. The skew angle shown on the standard plans is valid for signs on tangent sections of road regardless of offset distance. The skew angle may be adjusted to maintain brightness and avoid glare for signs on curved sections of road. The plans indicate which signs require a skew angle other than that shown in the standard plans.
Guidance. Unless otherwise stated in this Manual, signs should be vertically mounted at right angles to the direction of, and facing, the traffic that they are intended to serve.
Where mirror reflection from the sign face is encountered to such a degree as to reduce legibility, the sign should be turned slightly away from the road. Signs that are placed 30 ft. or more from the pavement edge should be turned toward the road. On curved alignments, the angle of placement should be determined by the direction of approaching traffic rather than by the roadway edge at the point where the sign is located.
Option. The standard skew angle is 93 degrees. However, skew angle may be adjusted to maintain brightness and avoid glare for signs on curved sections of road.
903.2.13 Sign Identification Decal (MUTCD Section 2A.20a)
Standard. Every MoDOT sign, regardless of the type or style, shall have an ID on the sign. At the time of installation of the new sign, the year and month shall be indicated.
Support. The Sign Production Center is currently silk screening or placing these IDs on the front side in the lower right hand corner of the sign.
903.2.14 Post and Mountings (MUTCD Section 2A.21)
Standard. Signposts, foundations, and mountings shall be so constructed as to hold signs in a proper and permanent position, and to resist swaying in the wind or displacement by vandalism.
Plastic/nylon washers shall be used between the heads of all twist fasteners (such as screws, bolts or nuts) and the sign sheeting to protect the sheeting from the twisting action of the bolt heads. Plastic/nylon washers are available through the Sign Production Center at no charge to the district.
Support. The latest edition of AASHTO’s Specifications for Structural Supports for Highway Signs, Luminaires, and Traffic Signals contains additional information regarding posts and mounting (see 903.19.11.2 for AASHTO’s address).
Option. Where engineering judgment indicates a need to draw attention to the sign during nighttime conditions, a strip of retroreflective material may be used on regulatory and warning sign supports.
Standard. If a strip of retroreflective material is used on the sign support, it shall be at least 2 in. in width, it shall be placed for the full length of the support from the sign to within 2 ft. above the edge of the roadway, and its color shall match the background color of the sign, except that the color of the strip for the YIELD and DO NOT ENTER signs shall be red.
903.2.15 Ordering Signs (MUTCD Section 2A.21a)
Support. Standard signs are those signs, which are described in the sign manual. They have been defined for size and message and given a specific sign number. Standard signs are typically made of a single piece of flat aluminum. Examples of standard signs are STOP signs, YIELD signs, SPEED LIMIT signs and alignment signs.
Structural signs are those signs that are constructed using extruded aluminum panels. These signs are typically erected on steel breakaway posts or on overhead trusses. Structural signs are typically found on the interstate, freeway and expressway systems. Typical structural signs are EXIT signs (E5-1) and the EXIT DIRECTION signs (E4-1) found on freeways.
Roll-up signs are signs that are made on a flexible, reflective material. They are primarily used for short-term traffic control signs for maintenance operations.
Signs not listed in this manual are considered special signs. See Figure 903.2.15 for Special Sign Requisitioning Process flowchart.
When ordering signs, there are several optional features available. These features are primarily related to vandalism control and are the following:
Protective Film: It is our intent to provide a system that will allow for the cleaning and removal of graffiti, dust and pollution from the sign surface. A protective overlay film is durable, solvent resistant and completely transparent. At this time, the cost to apply this film to all signs is prohibitive. If the district has certain locations that require sign replacement due to paint or graffiti, this film will allow the sign to be cleaned instead of replaced. Contact the SPC for information on the cost and benefits of the protective film.
Plastic Signs: In areas where there is a problem with theft of aluminum signs, it is possible to make standard ground mount signs on a plastic blank.
Standard. A requisition shall be submitted when ordering signs. General Services form E-82 shall be completed with the quantity, sign number, size and description indicated for each sign ordered. If the sign is needed on a rush or priority basis, this should be clearly indicated on the requisition.
An electronic requisition for structural signs shall be accompanied with detailed drawings of the required signs each on a separate page. Information for these signs shall include sign legend and roadway type. It shall also include on the requisition whether the signs are shoulder-mounted or overhead-mounted signs. If the signs have any pre-existing size restrictions, this shall also be noted on the requisition. If the district requires knowledge of the exact size of signs prior to fabrication, this shall be noted on the requisition.
Figure 903.2.15. Special Signs
Traffic shall approve all requisitions for special signs before fabrication. Special signs shall be on a separate requisition from in order to reduce delay in shipping, other sign types while the special sign is being reviewed. If a special sign is required, a description of the sign including color information, the sign's proposed location, and the reason for its use should be forwarded to Traffic for approval.
At the time of manufacturing, a detailed drawing of these special signs shall be forwarded to the district. The SPC will produce annually a listing of approved special sign numbers and legends.
Guidance. If the structural sign is a replacement for an existing sign, dimensions of the existing sign should be provided if possible. After fabrication a detailed drawing of the sign should be forwarded to the district sign shop that should be retained for future reference.
General Services orders roll up signs on a yearly basis. A requisition is to be submitted by the district.
If either of the two vandalism control features is needed on a sign it should be clearly indicated on the sign requisition.
The SPC will ship the sign order to the district, and upon receipt of a sign order, the district should inspect the signs for damage and to verify the quantities, types and legends of the signs. If problems with the order are found, the district should notify the SPC of the problems.
Option. The special sign request may include a sketch of the proposed sign and/or a picture of the problem location. A plan for evaluating the effectiveness of the special sign may be requested by Traffic.
903.2.16 Signing Paid for by Others (MUTCD Section 2A.21b)
Support. Under various policies, including Traffic Generator Signing, Custom City Limit Signing and College Signing, standard signs may be installed at the cost of the requesting party. See Figure 903.2.16.1 for flowcharts outlining the process for a new sign request and signing already in place.
Standard. Once the exact legend, quantity and location of the necessary signing is known, Traffic shall prepare an estimate for the cost of installation.
If the requesting party agrees to the cost estimate, a TR-15 contract shall be executed between the district engineer and requesting party. Upon execution of the TR-15 contract, the requesting party shall remit the full amount to the district. All funds shall be made payable to “Director of Revenue – Credit Road Fund”. If applicant requires a MoDOT invoice for payment, the district shall contact the Controller’s Office at the Central Office for assistance and use the Interagency Invoice Request form (See Figure 903.2.16.2 for this form).
Upon receipt of the funds, the signs shall be ordered and scheduled for installation. The district traffic office shall forward the funds to the district Business and Benefits personnel, along with the proper coding to ensure proper reimbursement to the district traffic budget.
Figure 903.2.16.2. Signing Paid For By Others (Sheet 2 of 2)
903.2.17 Contract Signing Field Checks (MUTCD Section 2A.21c)
Support. It is suggested that district traffic personnel, in conjunction with construction and/or design personnel, conduct field checks of contract signing as soon as the roadway has been roughed-in to the extent that the actual visibility and effectiveness of each sign can be determined.
903.2.18 Maintenance (MUTCD Section 2A.22)
Support. The storing methods are in place to prevent damage to the sign sheeting. Storing signs wet or horizontally will damage the retroreflective elements of the sheeting. MoDOT has a warranty for the sign sheeting, but improper storage will void the warranty.
Standard. Should packaged signs become wet, they shall be unpacked immediately and allowed to dry. Signs shall always be stored indoors on edge. New signs shall be stored in a cool, dry area to prevent moisture damage.
Guidance. All traffic signs should be kept properly positioned, clean, and legible, and should have adequate retroreflectivity. Damaged or deteriorated signs should be replaced.
To assure adequate maintenance, a schedule for inspecting (both day and night) and replacing signs should be established. All employees whose duties require that they travel on the roadways should be encouraged to report any damaged, deteriorated, or obscured signs at the first opportunity.
Weeds, trees, shrubbery, and construction, maintenance and utility materials and equipment should not obscure the face of any sign.
A regular schedule of replacement of lighting elements for illuminated signs should be maintained.

 |
903.2.19 Sign Inspection and Inventory (MUTCD Section 2A.22a)
Standard. A sign maintenance program shall be established for all routes within our systems. All signs on all routes shall be inspected once a year as follows:
A. Even numbered years a daylight inspection shall be performed.
B. Odd numbered years a night inspection shall be performed.
District database information containing sign logs for interstate, primary and supplementary systems shall be submitted to Maintenance office by July 1 of each year. It is the intention for this Division office to retain only the current year's sign logs. Each district shall retain copies of previous sign logs. The sign logs sent to the Traffic Division as required by the due date list shall be copies of each district's sign logs with the district retaining the master and a backup.
Guidance. Appropriate district personnel should perform the inspection of the interstate and primary systems. The sign inventory process is typically:
A. The sign inspection log shall include every sign on all routes within our system.
B. The exact message of those signs classified as guide signs shall be provided on the sign inspection log with no abbreviations.
C. Signs other than guide signs may be abbreviated. Care should be used in abbreviations that there will be no misunderstanding as to their meaning.
D. For those signs within an assembly, such as a junction assembly, the log should reflect the total number of signs within that assembly.
E. Trailblazer signs for LOGO signs should be logged using the corresponding generic service panel (i.e.: Gas LOGO D9-7G, Food LOGO D9-7F, Lodging LOGO D9-7L, Camping LOGO D9-3, Attractions LOGO D9-7a).
F. Signs requiring maintenance should be noted on the log.
Sign inspections should be performed and recorded as follows:
A. All signs should be logged if the sign’s face is visible for that direction of travel.
B. When a sign on an intersecting road with our system is logged, the other system should be identified.
- 1. If possible, identify the county road or city street by name and also note whether the intersecting road is a crossroad or on the right or left.
- 2. This data can be noted in parenthesis in the comments section.
- 3. Other items which should be noted in the comments section are whether the signs are mounted back-to-back and/or at 90 degrees to another sign.
C. Slashes should be used to differentiate between lines on a sign.
D. Arrows should be recorded as follows AH (ahead), LT (left), RT (right), 45LT and 45RT.
E. Routes must be designated with a prefix in order to efficiently sort the file.
- 1. The designation of "IS" will be used for Interstate Routes, "US" for U.S. Routes, "MO" for Missouri lettered and numbered routes and “BU” for Business Routes.
- 2. Lettered prefixes will immediately precede the route designation with no space or dash between the designation and the route.
- 3. When the route is a business or spur route, no designation will be necessary.
F. Signs within an assembly should be numbered from top to bottom and the columns will be lettered from left to right with the first column having no letter, the second column having letter "A" and so on. (See Figure 903.2.21 Standard Assembly Numbering for Route Marker Assemblies)
G. The log mile used to record the location of a sign should be the same as the log mile system established for accident data.
It is recommended an individual should be trained for proper mounting location and sign height, as well as inventory and sign ordering procedures. This individual would check to see that items marked on sign logs are accomplished within the year. The number of individuals trained in signing is based on district needs.
Sign quantities should be indicated by commodity code for each sign number within each organization. This is imperative to enable the inventory to be correctly maintained.
Support. The maximum inventory levels for all signs have been determined from the average annual usage for each type of sign. The maximum inventory represents approximately 1/3 of the average annual usage. This policy does not apply to signs used for emergency closures and routine maintenance operation traffic control signs.
The route designations used during the log process allow the records to be sorted by route without sorting out additional routes. For example, when sorting Route 3 without the designation prior to the number, one would also access Routes 35, 350 etc.
Examples of the lettered prefixes for route designations would be as follows:
| Type | Route |
|---|---|
| IS | 435 |
| US | 40 |
| MO | 15 |
| RT | AA |
When the route is a business or spur route, no designation will be necessary. The nomenclature would be as follows:
| Type | Route |
|---|---|
| BU | 60 |
| SP | 5 |
903.2.20 Salvaged Signs (MUTCD Section 2A.22b)
Standard. All damaged aluminum signs, except for those that are severely mangled or bent, should be kept for reclamation. All aluminum signs that are reclaimable shall be delivered to Moberly Correctional Facility at Moberly, Missouri.
All steel signs shall be kept at the district and sold as scrap by the district. Before a steel sign is sold for scrap the sign face shall be defaced so that the sign can no longer be used.
Guidance. Signs should be delivered on normal workdays between the hours of 8:00 a.m. and 2:30 p.m. One day's notice of delivery should be given by calling the institution's clerk at (660) 263-3778, Ext. 442.
Support. All signs are the property of the Commission with the exception of TODS and signs installed by others. Proper procedures need to be followed for disposing and defacing of old, faded or damaged signs. We are not allowed to sell signs.
The Moberly Correctional Facility does not require signs to be banded or on pallets.
There are several available options of hauling these reclaimable signs to the Moberly facility. One option is to use district resources to haul these signs. Another option is to use the current contract carrier who is hauling signs to your location from the sign shop; or if General Services is hauling to your location you may use them.
The last two options of delivery systems will have certain restrictions for hauling of this product. Contact the service provider to ensure that you meet the requirements.
903.2.21 Response to Emergencies (MUTCD Section 2A.22c)
Support. Risk Management has established guidelines concerning the response to replacing signs that have been knocked down or otherwise lost, see Table 903.2.22.
Guidance. The Risk Management Manual should be consulted for the proper procedures to follow.
903.2.22 Median Opening Treatments for Divided Highways with Wide Medians (MUTCD Section 2A.23)
Guidance. Where divided highways are separated by median widths at the median opening itself of 30 ft. or more, median openings should be signed as two separate intersections.
