The Frederick Douglass Bridge will close in July and August to remove hundreds of feet of roadway and lower the structure as much as 20 feet in some places.
When the bridge reopens, there will be a new intersection at Potomac Avenue and South Capitol Street, pedestrian and bicycle walkways, and improved roadway access throughout the area. The District Department of Transportation believes these changes will begin the transformation of South Capitol Street into a new urban boulevard. The first phase of the project begins this weekend, when the northbound lanes close temporarily.
