Kansas Department of Transportation (KDOT), the City of Topeka, and the Metropolitan Topeka Planning Organization have completed a concept study on how to improve I-70 from the MacVicar Avenue interchange through downtown Topeka to the Adams Street interchange. This section of I-70 includes the Polk-Quincy Viaduct that was constructed approximately 50 years ago. The preferred alternative recommends reconstructing I-70 to meet current highway design criteria, improving the safety and efficiency of I-70 and its connections to the local street system, providing for future traffic demands, and balancing access to provide connections to Downtown, the Riverfront Area, North Topeka, and East Topeka.
