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 Topeka City Council approved a resolution in February stating the City of Topeka's priorities and preferences for the realignment and replacement of the viaduct.
Final design planning has been approved by KDOT and should begin in Fall of 2011. The process should take 3-4 years. Construction funds are not included in the current 10-year T-Works plan. It is expected that, with design work complete, this project should be highly competitive for funding in the next 10-year plan expected to start in 2021 and/or for major funding that might become available from another source.
