NEW ENGINEERING POLICY GUIDE

RECENT POLICY CHANGES IN THE EPG

MoDOT has made great strides to build a good transportation system and increase taxpayers' trust in its ability to deliver what was promised. The same innovative concepts such as practical design and design-build that were used to deliver those commitments, have made MoDOT a leader in the transportation industry. These forward thinking, innovative concepts were continued with the decision to incorporate all MoDOT's engineering manuals under a single cover. MoDOT is proud to present the new ENGINEERING POLICY GUIDE. This document is the result of a yearlong effort to combine the Right of Way, Design, Bridge, Construction, Traffic and Maintenance Manuals; providing a single reference for all engineering guidance. MediaWiki, the engine behind the Wikipedia on the World Wide Web, is the software used to deliver the new manual. A small HELP ARTICLE is included to assist you with some helpful hints on how to use the manual as well as other points of interest. This HELP ARTICLE will be expanded as questions arise. You will find this format easy to navigate and more pleasing to read.
