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]
Description
The entire bridge is 1,378 feet (420 m) in length. On the west (Lake Oswego) side, there is a 50-foot (15 m) deck plate girder approach span that was built in 1900 and moved to this location in 1931. In 1934, a 60-foot (18 m) open-deck trestle was built on this side of the river.[1] Holding the railway deck across the river are two 298-foot (91 m) through truss spans.[1] Completing the bridge on the east side in Oak Grove is a 668-foot (204 m) open-deck trestle.
Usage
Though the bridge is now used exclusively for active freight rail transport, some Portland-area commuters have urged that the bridge be modified to allow commuter rail or bicycle traffic.[4][5]
