The Missouri Department of Transportation announced plans Tuesday to reconfigure the interchange at Stadium Boulevard and Interstate 70. Construction on a new diverging diamond interchange will begin in mid-March along with other projects designed to alleviate traffic along Stadium Boulevard.

COLUMBIA — The contract for a $12.7 million project to widen part of Stadium Boulevard and create a new diamond interchange at its intersection with Interstate 70 has been awarded to a Columbia company, Emery Sapp and Sons Inc.

Construction could start as early as mid-March but no later than April 8 and could last until late 2014.

The project will widen Stadium Boulevard from north of Interstate 70 to south of Broadway and add two lanes to Bernadette Drive from Fairview Road to Beverly Drive, said Mike Dusenberg, District Project Manager with the Missouri Department of Transportation.

“There will be a lot of night work because of the volume of traffic,” he said. “There will also be single lane closures on Stadium and periodic closures of intersections, such as Worley and Ash.”

The additional lanes and intersections are proposed to alleviate traffic congestion. The weaving style of the diamond interchange will reduce the amount of conflict points.

Columbia will follow St. Louis, Kansas City and Springfield’s lead of using the French-style interchange.

This video from MoDOT  illustrates how this kind of diamond interchange works:

Construction of the interchange will take place toward the end of the process and will require closing the intersection of Stadium and I-70 for one weekend. The public will be notified, and Dusenberg said it won't be scheduled during a big weekend, such as  the Show-Me Games, a home football game or graduation.

The project is funded by a cost-share agreement between MoDOT and the City of Columbia. The department financed approximately $8.9 million and the city $8.2 million.

Aside from the $12.7 million construction contract, which was awarded by the Missouri Highways and Transportation Commission, the $17 million project covers property right acquisition, engineering costs and utility relocation.
