History

The St. Paul Bridge and Terminal Railway was formed by the St. Paul Union Stockyard Company,[2] which was controlled by Swift and Company, the meat packing industry. The purpose of the railway was to switch freight from St. Paul into the stockyards in South St. Paul. The railway was leased to the Chicago Great Western Railway.[3] The CGW was merged into the Chicago and Northwestern Railroad system, along with the Chicago, Rock Island and Pacific Railroad. The Rock Island "Spine Line" and CGW line to Oelwein and Kansas City ran in parallel in South St. Paul. The Union Pacific Railroad purchased the assets of the C&NW.

Present day usage

The current Union Pacific Railroad Albert Lea Subdivision from Des Moines, the former Rock Island "Spine Line", enters the Twin Cities area and terminates in a yard in South Saint Paul. From this area, traffic to downtown St. Paul takes two routes: one across this bridge, with yards on the east side of the river south of Dayton's Bluff; and the other route using the St. Paul Union Pacific Vertical-lift Rail Bridge into downtown St. Paul.

Incidents

On October 26, 2017, a towboat struck a stationary bridge pier.[4][5] The towboat was the "Cooperative Venture," owned by American River Transportation Company. It was moving several barges with dry goods but nothing was spilled. Repairs begin shortly afterward. Traffic was routed to the St. Paul Union Pacific Vertical-lift Rail Bridge, and other locations.

On August 8, 2018, a train carrying oil across the bridge derailed, puncturing an oil tanker car and spilling 3,200 gallons of oil into the Mississippi River.[1]
