Route 740 (Stadium Boulevard) Improvements

Construction is under way on a project to improve Route 740 (Stadium Boulevard). The improvements include building a new interchange at I-70 – the first diverging diamond interchange to be built in central Missouri. In addition to the new interchange, the project will widen Stadium Boulevard from just north of Interstate 70 to south of Broadway. The work also includes widening Bernadette Drive from Knipp Street to Beverly Drive.  The construction cost is estimated at $12.8 million. The improvements are being funded by MoDOT, the City of Columbia and three transportation development districts. The project is scheduled to be completed in winter of 2014.

Route Z Road and Bridge Improvements

The Missouri Department of Transportation plans to make road and bridge improvements along Route Z during the 2013 construction season.  The Route Z project has three components:  resurfacing Route Z and adding shoulders from I-70 to St. Charles Road; building a roundabout at the intersection of Route Z and St. Charles Road; and replacing the Route Z bridge over Interstate 70.  The work is designed to improve safety and accommodate an expected increase in traffic associated with the new Battle High School.

U.S. 63 and Route H Interchange

The Missouri Department of Transportation proposes to construct a diamond interchange at U.S. 63 and Route H near the Columbia Regional Airport in Boone County. The project also includes constructing new southbound lanes from just north of Route 163 to Route H in Columbia. An outer roadway would be created using the current southbound lanes. This would allow for the removal of several crossovers to improve safety.
