The Union Street Railroad Bridge is a Pratt through truss, with a vertical lift bridge in Salem, Oregon. It carried train traffic across the Willamette River.

Finished in 1913, the Union Street Railroad Bridge was constructed by the Waddell & Arrington Engineers firm. They used their patented lift bridge design for the Salem, Falls City and Western Railway. It carried passenger and freight trains until 1945 when the regular service of the line ended.

In 2003, the Union Street Railroad Bridge was acquired by the City of Salem. They allotted a $550,000 fund for maintenance and $3.2 million for renovation and conversion. The project was finished and successfully turned the bridge to a pedestrian and bicycle bridge. It opened to traffic in May 2010.
