The U.S. 77/I-70 interchange improvement in Geary County was one of the projects approved in KDOT’s April letting. The existing interchange will be retrofitted into a diverging diamond interchange, which is a cost effective solution to improve safety and to handle a high volume of left turn movements at the ramps.
Diverging diamond interchanges have fewer conflict points (less opportunities for crashes), better sight distance at turns, increased left turn lane capacity, less driver confusion and it makes enter a ramp the wrong way extremely difficult. Construction is expected to begin this summer on the U.S. 77/I-70 interchange and be completed by December 2016.
Two diverging diamond interchanges have been built in Kansas – one at I-35 and Homestead Lane near Gardner and one at I-435 and Roe Avenue in Overland Park with six more either under construction or planned for construction.
