Massachusetts Avenue Bridge, Spanning Rock Creek & Potomac Parkway, Washington, District of Columbia, DC

Significance: This bridge, on axis with Massachusetts Avenue, replaced an earth-fill crossing that had been constructed in 1901; it was breached by a culvert through which a narrow two-lane road later passed. That viaduct constricted the traffic flow of the Rock Creek and Potomac Parkway and obstructed the open-valley landscape. The design of the new bridge allowed the parkway to pass underneath its large arch, and it harmonized with the pre-existing bridges over Rock Creek. The same team of designers was responsible for this bridge as for the contemporary K Street Bridge.
