Kansas City Divergabout Project

Improving traffic flow, reducing delays, and improving safety for everyone on the road resulted from a $17.8 interchange concept built by the Missouri Department of Transportation for two projects at U.S. Highway 50 and Interstate 49 in Grandview; an interchange called a “divergabout.”

A “divergabout” creates traffic pattern specifically tailored for interchanges with high traffic volumes and increased risks of serious crashes. The concept takes a divergent diamond and a roundabout and combines them into one.

Due to a nearby water park and other attractions, MoDOT knew a typical design solution would not be practical for this highway interchange, which is why the agency chose to built this first of its kind in the world “divergabout” instead.
