Park Avenue 4 to 3 Lane Conversion Project

Update MAY 3, 2021

The Park Avenue 4-to-3 Lane Conversion Project will move into the Washington Street and Park Avenue intersection starting Wednesday (May 5) when the west half of the intersection is closed to traffic. 


Manatts, the prime contractor for the Park Avenue project, anticipates that work in the intersection will continue through at least May 21, weather permitting. 


The west half of the intersection will be closed starting Wednesday as Muscatine Power & Water replaces a water main in the intersection. Once that is completed, Heuer Construction, Inc., will remove and replace the pavement. City officials indicate that the west half is tentatively scheduled to be completed by May 13, weather permitting. 


Once the west half is completed, the contractor will close the east half for pavement removal and replacement.


Construction Detour

Traffic on Park Avenue is currently restricted to the western two lanes as work continues in Stage 2 (the east side of Park from East 4th to Washington). North-South traffic on Park Avenue will be permitted through the Washington Street intersection but traffic will not be permitted to turn onto Washington Street. 


Highway 22 westbound traffic will be detoured onto University Avenue and onto Colorado before returning to Park Avenue. Local traffic only will be permitted past University Avenue while the intersection is closed.


Eastbound traffic on Washington Street will be detoured onto Cypress, to Isett, and to Clay before returning to Park Avenue. Local traffic only will be permitted past Cypress while the intersection is closed.

Other Park Avenue Project news:


The new traffic signals at the intersection of East 2nd Cypress Streets are now in “flashing red” mode and will continue in that mode until all traffic signals that are part of the Park Avenue 4-to-3 Lane Conversion Project have been installed, timed, and made operational.


The traffic signal mast arms and pedestrian poles are being installed in the east half of the East 5th Street intersection this week. Work on the west side traffic signals began Monday (May 3) when Taylor Ridge Drilling and Tri-City Electric completed the mast arm foundation. Tri-City Electric anticipates returning to put up the mast arm and mast arm signals on the west side either May 7 or May 10.


Full depth patch on the west side of Park Avenue is progressing with concrete work continuing from Washington Street south to East 4th Street.


Lane restrictions are currently in place with the west side two lanes closed to traffic. The east side two lanes are open with one lane of traffic in each direction. The lane restrictions will continue until full depth patching is completed in this stage of the project.


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.

Conversion Safety

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.
