Cedar Wapsi Road Bridge Project

Black Hawk County Engineer's office is planning the replacement of the Cedar Wapsi Road bridge over the Cedar River. The existing bridge was built in 1961 and is 651-ft long and 24-ft wide. This project is scheduled for construction in the 2019-2020 construction season and is estimated to take two years to complete.

Several environment and historical studies were completed along with a Type, Size and Location Study (full reports are below) which outlined both alternatives for the proposed bridge.  

At the April 4, 2017 Board of Supervisors meeting, the Board voted in support of constructing Alternate #1, replacing the new bridge in the current location at an estimated cost of $6.5 million. This will result in the bridge being closed for the duration of the project (Meeting Minutes).

Construction Detour


As part of Alternate #2, building the new bridge in the current location, traffic will be detoured during construction in 2019 & 2020. The posted detour will follow Union Road to Winslow Road to Maple Street in Janesville to Highway 218.

​Project Studies & Reports
​Type, Size and Location Study

​The type, size and location study was completed by AECOM of Waterloo, Iowa in April 2016. This report established two design alternatives for the size and location of the proposed bridge.
  • Alternate 1, a 677'-0" long x 40' wide bridge would be built in the location of the existing bridge.
    • Estimated cost: $6.5 million
  • Alternate 2, a 690'-0" long x 40' wide bridge would be built 55 feet to the south of the existing bridge. This would allow for existing traffic to be maintained for much of the construction project.
    • Estimated cost: $7.3 million

Endangered Species Studies


Black Hawk County is required to minimize or avoid impact to State and Federally endangered species. As part of this we have conducted several studies to determine the potential impact to those endangered species. These studies can be seen below:

Wetland Delineation Study


As part of this project Black Hawk County is required to determine and rebuild any disturbed wetlands in coordination with the United States Army Corps of Engineers. A wetland delineation report was completed by Stantec Consulting Services of Independence, Iowa in July 2016.

Archaeological Studies

Archaeological studies were completed by Two Rivers Archaeology of Anamosa, Iowa in 2016. Black Hawk County is coordinating with the Iowa Department of Transportation and the State Historic Preservation Office to determine and mitigate or avoid any areas of historic significance that could be affected by the project.
