The Kansas Department of Transportation (KDOT) selected TranSystems to design the Interstate 235 (I-235) interchange to accommodate safety and operational problems identified from a study and support a more efficient and resilient roadway system to better accommodate current and projected traffic volumes. As one of the most significant roadway infrastructure projects in Kansas history, TranSystems addressed several of the most congested sections between I-235 and U.S. Route 54/U.S. Route 400 (US 54/500), with minimal impact to the community, by implementing a Smart Work Zone to ease congestion and inform drivers. During certain phases where capacity was greatly constrained, the need for alternative routing was identified. Thus, variable message signs were deployed on the side roads that allowed users to divert at key locations and use the street network or other routes before entering the access-controlled freeway. By integrating portable, changeable message signs on key arterial routes feeding onto US54/400, better diversion was accomplished.
