The I-80 interchange at Alice’s Road Grand Prairie Parkway between Waukee and West Des Moines is scheduled to open Dec. 1, the Des Moines Register reports. The interchange is a diverging diamond, where traffic temporarily runs on the left side of the road to eliminate left turns across traffic. It’s the first exit of its kind in Iowa, just as Mills Civic Parkway was the first SPUI (single-point urban interchange) in Iowa in 2003.
The exit adds a western outlet/inlet for Dallas County’s continuing urban sprawl. It is the first new exit to open in Iowa since Ankeny’s Northeast 36th Street exit on I-35 Nov. 20, 2012.
