The I-70 Polk-Quincy Viaduct was constructed in the late 1950s. Since then, bridge condition deteriorated, traffic volumes increased, highway design criteria changed and the surrounding area has undergone development. The I-70 Polk-Quincy Project, spanning from MacVicar Avenue to 6th Street, will replace the aging viaduct, ease traffic congestion and improve safety.

Property Appraisals, Right-of-Way Acquisition In Progress Now

Property appraisals for the right-of-way acquisition process are underway for the Polk-Quincy Viaduct reconstruction project. This project will flatten the tight curve near 3rd Street, which requires the roadway to move 200 feet to the north. This may require acquisition of private property, including appraisals, just compensation analysis, written offers, payment and relocation if needed. Representatives from the acquisition team, O.R. Colan Associates, will be contacting affected property owners in the upcoming weeks and months.

On October 13, 2021, Governor Laura Kelly joined Kansas Department of Transportation Secretary Julie Lorenz and Topeka Mayor Michelle De La Isla to sign a formal partnership agreement for the long-awaited Polk-Quincy Viaduct project in Topeka. 

The agreement is a Memorandum of Understanding marking the formal project partnership between KDOT, City of Topeka, Shawnee County, Metropolitan Topeka Planning Organization, Topeka-Shawnee County Riverfront Authority, Topeka Metropolitan Transit Authority and the Greater Topeka Partnership. It commits the partners to cooperatively work towards implementation of the I-70 Polk-Quincy Viaduct Project.   

"As a long-time Topeka resident, I understand the significance of the Polk-Quincy project, and what a game-changer it will be for Topekans and for those traveling on I-70," Governor Kelly said. "I am eager to add my name, in representation of this administration and the IKE transportation plan, to the partnership group strengthening the Polk-Quincy Viaduct for generations to come." 

The MOU reads, in part: "The partners further commit to remain focused on collaboration and supportive engagement, while helping to ensure that issues are resolved in a timely manner, information is being shared proactively, and that due consideration is given to each partner's unique goals and interests, and roles and responsibilities."

Governor Kelly and Secretary Lorenz originally announced the Polk-Quincy project in July as one of eight Expansion and Modernization highway projects in eastern Kansas—with a total investment surpassing $297 million—that have been committed to construction as part of the Kelly Administration's bipartisan transportation plan.

"Polk-Quincy will be a landmark project for this community and our state," Secretary Lorenz said. "KDOT is committed to being the best partner we can be as we make the front door to our capital city something we can all be proud of."
