RECENT POLICY CHANGES IN THE EPG

The Park Over the Highway (CityArchRiver 2015) Project continues to progress over I-44. Work on the project will last through fall 2015. Maintc. Workers Clay Delcour (left) and Seth Dudley clean up chunks of asphalt scoured from Webster County’s Rte. A bridge over James River during the widespread flooding in June. District Bridge Engineer Dave O’Connor reviews a form used to record his inspection of one of many culverts in Hickory County. 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 20 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. Emery Sapp & Sons employees install girders on the northbound half of the new Crossroads Interchange bridge over I-44/I-49 near ‎Joplin. Traffic is now moving in both directions in all lanes.
