Boulder Bridge, Spanning Rock Creek at Beach Drive, South of Joyce Road, Washington, District of Columbia, DC

Significance: Boulder Bridge is one of the earliest extant bridges in Rock Creek Park. Constructed in 1902, the bridge exemplifies the idea of rustic architecture in the early twentieth century National Parks. It is a Melan reinforced concrete arch bridge with a unique boulder facing. The boulder facing blends into the bridge's surroundings, creating a structure that is both functionally and aesthetically complimentary to the natural setting. Also, the length of the span and the size of the boulders make it unique even among other stone-faced bridges.
