RECENT POLICY CHANGES IN THE EPG

Gerald Hanlin, a Troy area Senior Equipment Technician and an ASE-certified mechanic, rebuilds a snow plow truck’s motor. Kris Marshall, an El Dorado Springs area Senior Maintenance Worker, repairs cracks on Cedar County Route 32. 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. Millions of 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. D5 Transportation Project Designer Bob Jany discusses plans for a new interchange on Route 179 in Jefferson City with a member of the community. George Brett, a career-long Kansas City Royal and Baseball Hall of Fame inductee, signs a uniform on the new George Brett Bridge. The bridge is 18 ft. wider and 14 ft. longer than the old bridge and opened just 75 days after the old bridge came down following the KC Chiefs' extended season.
