Innovation Description and Benefit:

The district had accident issues on the Route 63 shared 4 lane south of Rolla in the interim condition before final stripping was placed. Shared 4 lanes routes are very difficult to “tab out” in a manner that travelers understand the proper lane use during the resurfacing process. When the district programmed the resurfacing of the Route 5 shared 4 lane in Laclede county, an alternate method for the traffic control was established to alleviate accident issues. The route was temporarily converted to two-lane use, allowing for staging of construction on segments of the route and leave two lanes open. This method has reduced the number of accidents, allowed most construction without lane drops, allowed majority of route to be completed during daytime hours rather than nightwork.
