MISSISSIPPI RIVER BRIDGE AT LANSING

History of the Black Hawk Bridge

The iconic bridge that carries travelers across the Mississippi River from Lansing, Iowa, to rural Crawford County, Wisconsin, has a history full of pride and more than a little intrigue. Here are some of the highlights.

1898

  • Local tradition dates the concept of the bridge back to 1898 and is attributed to two gentlemen named J.P. Conway and Tom Bakewell.

1916

  • Initially, the effort was organized under the Interstate Bridge Company in 1916.
  • The name later changed to the Lansing Bridge Company, and ultimately the organization would become the Iowa-Wisconsin Bridge Company.

1928

  • Stock in the Iowa-Wisconsin Bridge Company goes on sale to fund the project.

1929

  • The foundational work for the bridge was started.

1930

  • The bridge design changes from a suspension bridge to a cantilevered through truss design.

1930-1940

  • Ownership of the bridge is contested, and financial difficulties are noted.

1939

  • “Major repairs” are done to the bridge.

1945

  • In March, the Fern, an ice cutter on a mission for the military, creates an ice dam that causes slough bridge damage that cannot be repaired by the Iowa-Wisconsin Bridge Company.
  • Slough bridges were closed until repairs can be made.

  • Repair costs are estimated at $600,000, and estimates for a bridge replacement come in at $2M.
  • Talks begin for the states of Iowa and Wisconsin to take over ownership of the bridge.

  • Under the ownership of the states of Iowa and Wisconsin, the bridge is reopened without a toll.

1978

  • There are numerous documented and undocumented strikes to the bridge piers and abutments across its history, but this one was significant. On Aug. 31 at 3 a.m. the Ed Renshaw grain barge strikes the bridge. Nine of its 15 barges block the river channel.

1990s

  • The bridge is maintained with various rehabilitation and repair projects.
