The Lake Oswego Railroad Bridge (also known as the Union Pacific Railroad Bridge at Lake Oswego and formerly as the Southern Pacific Railroad Bridge at Lake Oswego) is a truss railroad bridge that spans the Willamette River between Lake Oswego, Oregon and Oak Grove, Oregon. Owned by the Union Pacific Railroad, it is currently leased by the Portland and Western Railroad and carries the Milwaukie branch.
History
The bridge was built in 1910 by the Beaverton and Willsburg Railroad, a subsidiary of Southern Pacific Company, in response to the desires of Portland city planners for an eastside railway bypass to keep rail traffic out of downtown Portland.[1] Robert Wakefield, later involved with the Steel Bridge, was the builder.[2][3] With its acquisition of Southern Pacific in 1996, Union Pacific Railroad assumed ownership of the bridge. Currently, the bridge is operated by the Portland and Western Railroad under a lease from Union Pacific.[4]
