20th Avenue NE Bridge

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.

It supports an 18 ft (5.5 m) reinforced concrete roadway.

Beginning on March 11, 1975, a four-month trial began wherein the bridge was closed to vehicular traffic.

[5] The trial period was successful and the bridge has been closed to vehicle travel ever since,[6] but it is accessible by pedestrians and cyclists.
