Union Street Railroad Bridge
Salem, Marion County, Oregon, 97301
The Union Street Railroad Bridge is a vertical lift, Pratt through truss bridge that spans the Willamette River in Salem, Oregon, built in 1912–13.
The bridge has two towers that rise an additional 65 feet (20 m) above the 35-foot (10.7 m) tall structure of the bridge's trusses, a 134-foot-long (41 m) center lift span, and a total length of 722 feet (220 m), excluding the 850-foot (260 m) timber trestle on the western end. The bridge's five spans sit atop five concrete piers designed to rise 35 feet (10.7 m) above mean low water, which was intended to hold the rails 5 feet (1.5 m) above the highest possible flood waters. The lift span was designed to provide a 55-foot (16.8 m) clearance during high water conditions.
The lift span has been inoperable since 1980, and sometime after 1980 the operator's house – which sat atop the lift span – was removed.
It was last used by trains in the early 1990s and was sold for one dollar in 2003 to the City of Salem, which converted it to bicycle and pedestrian use in 2008–2009.
