94-year-old bridge over Mississippi River demolished

At least 100 cars lined the roads south of Lansing, Iowa as people gathered to watch the Black Hawk Bridge come down on Friday.

Originally constructed in 1931, the Black Hawk Bridge was demolished due to safety concerns related to the construction of a new crossing between Lansing and rural Crawford County.

For many lifelong residents of the Driftless, driving over the bridge’s steel grate was a unique and nostalgic experience.

“Kids that go across that bridge, they hear that sound, they have the bumps, they can fly up in the air a little bit,” said Laurie Manning of Lansing.

She was one of around two dozen people from Wisconsin, Iowa and Minnesota gathered at the Driftless Area Education and Visitor Center just over a mile south of the bridge. People huddled together against the cold on the center’s porch and kids played in the snow while waiting for the demolition, which was delayed by an hour and a half.

Manning grew up across the river in De Soto and makes the drive back frequently to visit her parents and other family. Since the Black Hawk Bridge closed earlier this fall, she’s had to rely on the river ferry contracted by the Iowa Department of Transportation or drive 30 miles to the next bridge in Prairie du Chien or La Crosse.

But Manning is most upset about not seeing the bridge every morning on her commute.

“I don’t want to visualize it not being there when I come into town,” she said. “The sun rises over here, it hits that bridge, and it just glows.”

Manning said she’s been preparing for the demolition since the Iowa DOT announced in July that the bridge would be taken down early.

Officials said in July that construction on the new bridge made the old crossing a threat to public safety and to construction crews. The bridge had already gone through two temporary shutdowns due to safety concerns earlier this year.

Ross Geerdes, director of the Allamakee County Conservation Board, said they’ve seen an influx of visitors at the Driftless Center this year, many hoping to see the bridge one last time. His organization is working on an exhibit to remember the Black Hawk Bridge and its unique features.

“We have audio of cars going across the bridge, and we’re going to be able to play that audio for people,” Geerdes said. “Everybody has a different memory of it, but for me, it’s the steel grate, and being able to look up as you’re going underneath it in a boat, and seeing the cars go across, and that unique sound that it has.”

Geerdes said the Driftless Center works with around 20 different schools on both sides of the river, and losing the bridge may make field trips more difficult in the coming year. But he said many of their visitors are people driving the Great River Road, who will likely be better able to make the trek to the next crossing.

The Iowa DOT plans to continue the ferry service throughout the winter, using barges to break up the ice on the river. The new bridge is expected to be open in 2027.
