U.S. 61 to Close Overnight at Center Junction

Final Stages of Project to be Completed

SIKESTON – Construction of the diverging diamond interchange at Interstate 55 and U.S. Route 61 (mile marker 99) between Cape Girardeau and Jackson, Missouri, continues with nightly closures of U.S. 61 beginning Monday, Oct. 4 through Friday, Oct. 22.

Contractor crews will continue work on U.S. 61 as the diverging diamond interchange project nears completion. Beginning Monday, Oct. 4 through Friday, Oct. 16, diamond grinding operations will take place. From Monday, Oct. 18 through Friday, Oct. 22, crews will be striping the lanes in preparation for project completion.

Weather permitting, work will take place nightly, requiring a full closure of U.S. 61 from Orchard Road to Veterans Drive from 8:30 p.m. to 6 a.m. All interstate ramps will remain open to right turn movements only. Motorists should seek alternate routes during closures.

News Release > 




A $17,476,608 contract was awarded to Penzel Construction Co., Inc., for construction of a diverging diamond interchange and replacement of two Interstate 55 bridges at the intersection of Interstate 55 and Route 61 (Kingshighway/Jackson Boulevard) in Cape Girardeau County in January 2020.

What are the benefits of converting the existing interchange to a diverging diamond interchange?

Diverging diamond interchanges work well in areas of heavy traffic. Approximately 23,000 vehicles per day travel through the interchange. A major benefit of the DDI design is it allows motorists to make left turns without crossing in front of oncoming traffic. It will also improve traffic flow onto and off of the interstate ramps.
