RECENT POLICY CHANGES IN THE EPG

Construction continues on the Poplar Street Bridge on I-64 over the Mississippi River. Crews are working on placing the new overlay on the bridge and widening the ramp from northbound I-55 to the bridge. Above, Jefferson City’s Mayor Carrie Tergin (left) joins Structural Liaison Engineer Michele Atkinson for a selfie after declaring “Buckle Up Phone Down Day” in the city. The mayor knows how to promote a good thing! 400px 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 November, the numbers of hits are: 20. EPG 136 165179  10. EPG 751.5 227933 19. EPG 134 169980  9. EPG 600 260121 18. EPG 751.40 170196  8. EPG 616.23 269131 17. EPG 136.4 177544  7.
