Demolition, site work, paving and addition to a civil project in Kansas City, Kansas. Design plans call for site work for a road / highway; bridge / tunnel; for the demolition of a road / highway; and for paving for a bridge / tunnel.

As of March 14, 2024, this project is in the design phase. Although a firm timeline has not been establihsed, project letting is not expected to start prior to fall of 2024, and construction is not expected to start prior to spring of 2025. The closed solicitation has been included below for reference. The project expands I-70 from four lanes to six lanes from MacVicar Avenue to Topeka Boulevard, replaces the existing viaduct by flattening the curve on I-70 at Third Street and makes improvements for motorists traveling through or entering downtown Topeka. According to the Kansas Department of Transportation, the first phase of the project will begin this summer, continuing off and on through the summer of 2024. It will include demolition of acquired properties for right-of-way, archeological survey work and utility relocation, weather permitting. The second phase of the project is pavement maintenance and bridge deck patching on seven bridges along I-70 in downtown Topeka. This will allow the continued use of the roadway until the construction of the viaduct replacement begins. The pavement and deck patching will occur during the 2022 and 2023 construction seasons. Reconstruction and replacement of I-70 and the Polk Quincy Viaduct will occur in the final phase of the project, which is scheduled to begin in early 2025.
