The Park Avenue 4-to-3 Lane Conversion Project was substantially completed in late October 2021 following the completion of lane striping and activation of the new traffic signals.
Currently, the contractor is working to complete the Iowa Department of Transportation (DOT) punch list for the project. The first half, Colorado/Clay to Washington, has been completed with work now moving to the second half, Washington to the Mad Creek Bridge, starting Monday (April 4). Please use caution when driving through construction zones.
The improvements included in the Park Avenue 4-to-3 Lane Conversion Project will focus specifically on safety, including traffic lane reconfiguration that would change the road from four lanes (two operating in each direction) to three lanes (one lane in each direction and a center two-way, left turn lane) from Harrison Street to the Iowa 92 bridge. The project will also allow for 74 new sidewalk ramps that would be compliant with Americans with Disabilities Act (ADA) guidelines, full depth patching of the roadway, and an asphalt overlay.
Manatts,Inc., was awarded the $2,284,476.07 contract following the June 2020 Iowa Department of Transportation bid letting. IDOT will fund $1,297,714.00 of the project with the rest shared by the City of Muscatine and Muscatine Power & Water.

Research suggests significant safety benefits can be achieved through four-lane to three-lane conversion projects, including reduced crashes. Pictured below are common crashes that occur on four-lane, two-way traffic roads.
