	The RATE OUR WORK ZONE sign is designed to capture the traveling public’s expectation of MoDOT’s work zones through a [https://www.modot.org/work-zone-customer-survey MoDOT website customer survey].

	Placement location for the RATE OUR WORK ZONE, POINT OF PRESENCE and WORK ZONE NO PHONE signs are located in [https://epg.modot.org/forms/general_files/TS/Typical_Applications/SF-Begin-End_of_Project_Signing.pdf Supporting Figure: Begin/End of Project Signing].

	This sign is used on all projects unless the roadway is closed to traffic and the construction has no effect on existing roadways. District Engineers have discretion whether to use this sign on mobile and short-term projects, such as contract leveling course. One RATE OUR WORK ZONE sign will be placed approximately 500 ft. before the beginning of the project limits or the ROAD WORK AHEAD sign or ROAD WORK NEXT xx MILES sign, if used, when these signs are located outside the project limits for each direction of traffic affected by the project. On multilane highways, only one RATE OUR WORK ZONE sign is required for each direction of traffic affected by the project. The job estimate is to include the appropriate square footage of the sign as construction signing. See [https://www.modot.org/media/16892 Std. Plan 616.10] for sign layout.

	The RATE OUR WORK ZONE sign is available in two sizes depending on roadway conditions. The 48 in. x 24 in. sign is used on low volume routes that carry 400 AADT or less, on projects that have a duration of 4 weeks or less or in urban areas where there is insufficient right of way for a six foot wide sign. The 72 in. x 36 in. version of the sign is used in all other applications, but can also be used in place of the 48 in. x 24 in. sign if added emphasis is deemed necessary.

	~~===616.6.51.2~~ "Point of Presence" Sign===
	The POINT OF PRESENCE signs provides the traveling public the finished date of the project as promised by MoDOT.		The POINT OF PRESENCE signs provides the traveling public the finished date of the project as promised by MoDOT.

	This sign is to be used on projects deemed prominent by the district. One sign should be placed in each direction of traffic on state highways. This sign is not to be used on roadways that are closed to traffic or where the construction has no effect on existing roadways. The “Point of Presence” sign is to be placed in a visible area within the project’s limits provided its placement does not disrupt a sequence of signs (e.g., between ROAD WORK AHEAD, RIGHT LANE CLOSED AHEAD and RIGHT LANE CLOSED). If a visible location within the project is not available, this sign may be placed approximately 500 ft. before the ~~RATE OUR~~ WORK sign. Because of the sign’s width, flatter areas are preferable in order to avoid long post lengths in fill sections. The job estimate is to include the appropriate square footage of the sign as construction signing.		This sign is to be used on projects deemed prominent by the district.

At the district’s discretion, additional signs within the work zone may be enhanced with flags, however such practice should be infrequent.
