RECENT POLICY CHANGES IN THE EPG

Robertson Contractors employees slip form the barrier wall at the new Rte. 51 Little White Water Creek Bridge near Patton. Fronabarger Concreters employees replace the old tracks of the St. Louis Iron Mountain and Southern Railway crossing of MO Rtes. 25, 34 and 72 and U.S. 61 in Jackson. Work began to produce the new, much smoother crossing at 6 PM on Saturday and was completed by 4 PM the next day which avoided having the busy intersection closed through the week. Progress continues on the I-35 and Pleasant Valley Rd. interchange project in Clay County. The existing interchange is too small to accommodate the traffic volume of one of Missouri's fastest-growing areas. All construction will be complete by July 2017. 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 30 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 late April, the numbers of hits are: 20. EPG 136, 132964 10. EPG 616, 183158 19. EPG 134, 135444 9. EPG 600, 217176 18. EPG 751.40, 136389 8. EPG 616.23, 240816 17. EPG 751.50, 144625 7.
