The 20th Avenue NE Bridge (also known as the Ravenna Park Bridge) is a three-hinged, steel, lattice-arched bridge that spans a ravine in Seattle's Ravenna Park. It was designed by Frank M. Johnson under the direction of city engineer Arthur Dimock.[2] Built in 1913, the structure is both listed in the National Register of Historic Places and is a designated city landmark.[3][4]
The structure is 354 feet (108 m) long. It has a 250-foot (76 m) arch that rises 41 feet (12 m) over the ravine. It supports an 18-foot (5.5 m) reinforced concrete roadway. The road has been closed to vehicular traffic since 1975, but it is accessible by pedestrians.[2]
