U.S. Route 50 (Whitton Expressway) Roadway Improvements - Environmental Impact Study

The Missouri Department of Transportation partnered with Cole County and Jefferson City to complete an environmental impact study of the Whitton Expressway. The study examined improvements to address current and future needs for safety and capacity. The study also examined connectivity to the planned redevelopment at the Missouri State Penitentiary site.

U.S. Route 54 Corridor Intersection Improvements

MoDOT is making improvements to twelve intersections along the U.S. 54 corridor in Cole County, along approximately 8.5 miles between Route CC and Old Bass Road. Among similar highways, this section of roadway is ranked one of the highest in the state for the number of fatal intersection crashes.

Serious injuries have also resulted from crashes at intersections across the corridor. Many of the crashes involve vehicles from the adjacent roadways pulling into the path of vehicles on U.S. 54.

The project team has studied the corridor beginning in March 2010 and proposed a variety of engineering strategies to modify multiple intersections in an effort to improve safety. These adjustments will maintain traffic flow on U.S. 54, as well as to and from the highway.
