Park Avenue 4 to 3 Lane Conversion Project

Update JULY 13, 2021

The final section of full depth patching as part of the Park Avenue 4-to-3 Lane Conversion project is underway with the tentative schedule calling for the patching and intake modifications to be completed by July 16.

The final steps in the project will be milling, prepping, paving, and striping of Park Avenue from Mad Creek to Colorado. Prime contractor Manatts indicates that the milling of the south section from Mad Creek to Washington Street will begin on July 28 with work on this section continuing until completed.

That will be followed by the milling, prepping, paving, and stripping of the north section from Washington to Colorado.

Once stripping has been completed, the traffic signals at 2nd Street and Cypress, 5th Street and Park Avenue, Washington and Park Avenue, and Colorado/Clay and Park Avenue will be put into operational mode.

Manhole water valve adjustments and seeding will begin on August 12 with the project tentatively scheduled to wrap up by August 20, weather permitting. 


Drivers are reminded to slow down and use caution when travelling through the construction zone, obey traffic control devices, and be aware of workers. Use an alternate route if possible.


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.
