20th Avenue NE Bridge

The 20th Avenue NE Bridge is a steel arch crossing a ravine in Ravenna Park that links neighborhoods with its distinctive design. The structure carries pedestrians and cyclists over the natural depression while its framework remains visible from below, creating an interesting visual element within the park.

The bridge was built in 1913 by designer Frank M. Johnson and shows early engineering methods from the start of the 20th century. It entered the National Register of Historic Places in 1982 due to its importance as an American transportation engineering example.

This structure earned recognition on the National Register of Historic Places in 1982 as part of Washington's collection of significant transportation engineering achievements.

The bridge has been open to pedestrians and cyclists since 1975 and provides a direct link between residential neighborhoods. The path through the natural area is straightforward to use and accessible for various visitors.

The structure uses a three-hinged steel design that achieves maximum stability with minimal materials. This thoughtfully engineered system from 1913 allowed a lean structure to be built that continues to perform well today.
