Improving the Viaduct

The 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.

As part of T-WORKS, the state's current transportation funding program, the I-70 Polk-Quincy Viaduct Design project was selected to receive funds to continue the project and begin work on design plans. While no funding was identified for construction under T-WORKS, this will position the I-70 Polk-Quincy Viaduct project to be construction ready so that the project can move forward when funding becomes available.
