Honor Award – GBA, Lenexa, KS
Project: US-50 @ MO-291S Interchange (Divergabout)
Client: Missouri Department of Transportation
What started out as a simple bridge replacement project became an innovative interchange concept to improve mobility and facilitate future growth through a heavily traveled corridor. The concept, a divergabout, is a brand-new layout which includes a diverging diamond cross-over at one ramp terminal and a roundabout at the other. George Butler Associates (GBA) was hired by MoDOT to refine and optimize this unique concept for the US-50 at MO-291S interchange in the city of Lee’s Summit. The result of this approach is a design that alleviated traffic issues while providing long-term time and cost savings. Moving forward, the divergabout can serve as an innovative method to serve the public’s growing transportation needs.
