The Hawthorne Bridge is a truss bridge with a vertical lift that spans the Willamette River in Portland, Oregon, joining Hawthorne Boulevard and Madison Street. It is the oldest vertical-lift bridge in operation in the United States[1] and the oldest highway bridge in Portland. It is also the busiest bicycle bridge in Oregon, with over 8,000 cyclists[4] and 800 TriMet buses (carrying about 17,400 riders) daily.[1] It was added to the National Register of Historic Places in November 2012.[3][5]
