RECENT POLICY CHANGES IN THE EPG

MoDOT is repairing 15 bridges along I-470 from Blue Ridge Blvd. to I-70. Crews are progressing well on the Cedar Cr. Bridge in Lee’s Summit. (L to R) Sr. Traffic Studies Specialist Jeff Baird, a private citizen, Area Engr. Karen Yeomans and Proj. Manager Jenn Becker talk at a public hearing in Brentwood, MO about construction along Manchester Rd. between Lindbergh and Big Bend scheduled for 2020. 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. Perhaps you've wondered how many hits the most popular EPG articles have. As of early April, the numbers of hits are: 20. EPG 136 169099  10. EPG 751.5 237670 19. EPG 134 177018  9. EPG 616.23 273447 18. EPG 751.40 179275  8. EPG 600 275202 17. EPG 136.4 179447  7.
