AUGUST 25, 2020 Update

Lane restrictions are in place on East 2nd Street from the intersection with Iowa 92 to the intersection of 5th Street and Park Avenue in preparation for the start of work on the Park Avenue 4-to-3 Lane Conversion Project. The westbound two lanes have been closed to traffic with two-way traffic shifted to the eastbound lanes.

 Manatts, Inc., the prime contractor for the project, indicated that Heuer Construction, Inc., was to mobilize into the area and will begin full depth patching of the roadway sometime this week. Although a complete schedule of work activity has not been established with City of Muscatine project managers as yet, activity will center on full-depth patching at the present time.

 Part of the project is the replacement of traffic signals at four locations in the Park Avenue corridor including the ones on East 2nd Street at the intersection with Iowa 92. In preparation for the signal upgrade, the signals will be placed in flashing red and temporary stop signs will be placed at the intersection.

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


The Muscatine City Council approved the contract and bond for the Park Avenue 4 to 3 Lane Conversion Project at the July 16 meeting. The Iowa Department of Transportation opened bids for this project on June 16, 2020, with Manatts,Inc., the winning bid at $2,284,476.07 which was lower than the engineer estimates. IDOT will fund $1,297,714.00 of the project with the rest shared by the City of Muscatine and Muscatine Power & Water.

The proposed improvements 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). The City is looking to make these conversions on Park Avenue from Harrison Street to the Iowa 92 bridge. The lane reconfiguration will also allow for new sidewalk ramps.

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.
