|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. Innovative concepts, such as Practical Design and design-build, were used to deliver those commitments and have made MoDOT a leader in the transportation industry.
These forward-thinking, innovative concepts are reflected in the ENGINEERING POLICY GUIDE (EPG). This document provides a single reference for all engineering and engineering-related guidance by combining the former Right of Way, Design, Bridge, Construction, Traffic and Maintenance manuals.
MediaWiki, the engine behind the Wikipedia on the World Wide Web, is the software delivering the EPG. Over 40 million hits on the EPG endorse this format to be easy to navigate and pleasing to read. A small HELP ARTICLE is included to assist with helpful hints on how to use the EPG as well as other points of interest.
