The second phase of the Iowa Department of Transportation’s US 61/151 Peosta Channel Bridge Deck Overlay Project will begin on Monday, April 21. Crews will be improving the surface of the U.S. 61/151 bridge over the Peosta Channel north of 16th St.

The project will require the closure of the southbound lanes of U.S. 61/151 from the Wisconsin Bridge exit to the 9th St./11th St. interchange. Drivers going through the area can expect the following closures and detours:

• Beginning April 21: U.S. 61/151 Lane Closures
  • The inside lanes of U.S. 61/151 will close in both directions for the removal of median barriers.
• Beginning April 23: U.S. 61/151 Southbound Lanes Closed
  • Both southbound lanes of U.S. 61/151 will be closed. During the closure of the southbound lanes, northbound and southbound traffic will be merged into a two-way traffic pattern in the northbound lanes of the highway. The southbound entrance ramp from Kerper Blvd. to U.S. 61/151 will be closed, as will the southbound exit ramp at the 9th St./11th St. interchange. The southbound exit ramp for Kerper Boulevard and Chaplain Schmitt Island will be accessible during the project.

The Iowa DOT expects the bridge replacement project to be finished in August 2025.

If you have questions regarding U.S. 61/151 closures/detours, please contact the Iowa DOT at 563-927-2397. Please note, closure dates and times are estimates and subject to change without notice based on weather and contractor schedules.
