LANSING, Iowa – April 15, 2026 – The Iowa and Wisconsin Departments of Transportation are continuing to construct the Mississippi River Bridge Project at Lansing. The project is moving a previously announced controlled explosive demolition of one of the remaining piers to Friday, April 17. The demolition was delayed one day due to severe weather.
This demolition will use underwater explosives to demolish one of the concrete piers on the east side of the project near the Wisconsin landing. The demolition will require certain closures to ensure safety:
- The free car ferry service will be suspended for about five hours on the afternoon of April 17, likely starting at noon. The closure is due to the demolition and for coincidental ferry maintenance. Exact closing times and the eventual reopening will be announced through the project Facebook page at www.facebook.com/LansingBridge/ and will be noted on Iowa 511 at 511ia.org.
- The car ferry landings on both the Iowa and Wisconsin sides will be completely closed. There are no other highway or street closures planned in either state.
- The main navigational channel of the Mississippi River will be closed to recreational and commercial vessels within a safe radius around the bridge. Enforcement will be present to ensure boaters are outside of the clear zone during this blast. This closure will begin in the afternoon, and last around three hours. The Big Slough Boat landing will remain open during this time.
Area residents may hear the blast. However, the impact will occur underwater, so the sound may be muffled, and the blast may not be noticeable except very close to the river. There should be no impact to area homes or businesses from the blast.
The demolition could be further delayed to Saturday, April 18, due to weather or other considerations. Iowa DOT and WisDOT will issue updates about delays as needed.
