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 [[:Category:143 Practical Design|Practical Design]] and [[:Category:139 Design - Build|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 [http://sharepoint/sites/de/RealEstate/SitePages/Home.aspx Right of Way], [http://sharepoint/sites/de/Pages/default.aspx Design], [http://sharepoint/systemdelivery/br/pages/default.aspx Bridge], [http://sharepoint/systemdelivery/cm/Pages/default.aspx Construction], [http://sharepoint/systemdelivery/tr/Pages/default.aspx Traffic] and [http://sharepoint/systemdelivery/mt/default.aspx Maintenance] manuals. 
 
 
MediaWiki, the engine behind the Wikipedia on the World Wide Web, is the software delivering the EPG.  Millions of hits on the EPG endorse this format to be easy to navigate and pleasing to read.  A small [[:Help:Contents|'''HELP ARTICLE''']] is included to assist with helpful hints on how to use the EPG as well as other points of interest.

Our mission is to provide a world-class transportation system that is safe, innovative, reliable
and dedicated to a prosperous Missouri.


WELCOME
MoDOT’s three pillars of “Safety, Service and Stability” steer our leadership and employees. Our commitment to safety includes keeping both customers and ourselves safe. Our service includes providing outstanding customer service, delivering transportation solutions of great value and using resources wisely. Keeping roads and bridges in good condition, operating a reliable and convenient transportation system, and advancing Missouri’s economic development reflect our commitment to stability.

Innovative concepts, such as Practical Design and design-build, are used to deliver our commitments. These and other forward-thinking concepts shape the content of the ENGINEERING POLICY GUIDE (EPG). This document provides a single reference for all engineering and engineering-related Bridge, Construction, Design, Maintenance, Planning, Right of Way and Traffic guidance.
