The I-70 eastbound to I-35 southbound ramp bridge in downtown Kansas City has been temporarily closed for repairs. During a routine inspection, engineers found significant deterioration to the bridge's structure. Motorists are asked to find alternate routes for 2 to 3 weeks until the bridge is repaired and re-opened.

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.

On divided major routes, 20 mils of waterborne paint will be applied on both edge lines and centerline skips with 12 lbs/gallon of Type L glass beads. Also, routes with pavement markings in good condition in the spring will be omitted from that year’s striping program.

EPG 628 High Friction Surface Treatment (HFST)

2/25/15: HFST is a cost-effective way to increase the safety of road segments where vehicles frequently depart the traveled way due to polishing of the existing pavement aggregate or by way of slightly substandard geometry. MoDOT has piloted this technology with excellent results and this new article will place it into more mainstream usage.
