The 50 or so crossings of the Willamette River include many historic structures, such as the Van Buren Street Bridge, a swing bridge. Built in 1913, it carries Oregon Route 34 (Corvallis–Lebanon Highway) over the river upstream of RM 131 (RK 211) in Corvallis. The machinery to operate the swing span was removed in the 1950s. The Oregon City Bridge, built in 1922, replaced a suspension span constructed at the site in 1888. It carries Oregon Route 43 over the river at about RM 26 (RK 42) between Oregon City and West Linn.The Ross Island Bridge carries U.S. Route 26 (Mount Hood Highway) over the river at RM 14 (RK 23). It is one of 10 highway bridges crossing the river in Portland. The 3,700-foot (1,100 m) bridge is the only cantilevered deck truss in Oregon.
Tilikum Crossing is a 1,720-foot (520 m) cable-stayed bridge that carries public transit, bicycles, and pedestrians, but no cars or trucks, over the river. It opened for general use on September 12, 2015, becoming the first new bridge built across the river in the Portland metropolitan area since 1973.Further downstream is the oldest remaining highway structure over the Willamette, the Hawthorne Bridge, built in 1910. It is the oldest vertical-lift bridge in operation in the United States and the oldest highway bridge in Portland.  It is also the busiest bicycle and transit bridge in Oregon, with over 8,000 cyclists and 800 TriMet buses (carrying about 17,400 riders) daily.
Another historic structure, the Steel Bridge, further downstream, was "the largest telescoping bridge in the world at the time of its opening" in 1912. It carries trains on its lower deck, MAX (Metropolitan Area Express) light-rail trains and motorized vehicles on its upper deck, and foot and bicycle traffic on a cantilevered walkway attached to the lower deck. When small ships must pass under the bridge, its double vertical-lift span can raise a lower railway deck without disturbing traffic on the upper deck. Operators can raise both decks as high as 163 feet (50 m) above the water. The...
