La Crosse Rail Bridge is a swing bridge that spans the Mississippi River between La Crescent, Minnesota and La Crosse, Wisconsin.
The original bridge was one of the first 15 bridges across the Mississippi River. It was designed and built in 1876 by Chicago, Milwaukee, St. Paul and Pacific Railroad.
Prior to the construction of any swing bridges, the Mississippi River connected the country north to south, but was an obstacle for those going east to west. The railroad relied on ferry boats to transport rail cars across the river into La Crosse, which cost a considerable amount of money and time. In addition, many of the ferry boats were unreliable because they had no fixed scheduled. In the early 1800s, it was difficult to construct bridges, as they needed to provide enough clearance for the abundance of steamboats on the river. In the winter months when the river froze over and boat traffic stopped, the railroad would lay down seasonal tracks across the ice and remove them by spring.
Then in 1856, the first swing bridge to span the river was constructed in Rock Island, Ill., to solve the problem. Only a few days after the bridge was opened, a steamboat crashed into it. Some people think it might have been on purpose because the steamboats did not care for these bridges. The boat and bridge caught on fire, and the steamboat owner sued for damages, claiming the bridge was a hazard to navigation. Fortunately for the railroad, it was defended in court by an Illinois lawyer: Abraham Lincoln.
Lincoln won the case for the railroad, arguing that a person has a much right to build a bridge to cross a river as another person has to travel up and down the water. This victory led to the construction of even more swing bridges, including the L4B.
Over the years, L4B has gone through many changes, with a major update in 1902 when it was reinforced with iron. The initial construction of L4B began in June 1876 and was completed five months later in November. At the time, the bridge cost $500,000 to build, but paid for itself in a few years, with the railroad saving $90,000 a year in river tolls.
The bridge is located over the west channel of the Mississippi River near Shore Acres and links to Minnesota Island. A second bridge connects Minnesota Island to the Wisconsin shore across the Black River. L4B, however, is located entirely on the Minnesota side of the river and is 1,050 feet, 11 inches long.
The swing span has a humpback truss, while the two adjoining spans are flat-top fixed through trusses. Amtrak's Empire Builder crosses this bridge.
