Closures of Q Street SW @ Half Street SW

These closures are required for construction activities associated with the following DDOT projects:

 

South Capitol Street Corridor Project - Frederick Douglass Memorial Bridge

The South Capitol Street Corridor Project calls for replacing the Frederick Douglass Memorial Bridge and transforming related sections of the urban freeway into a beautiful scenic boulevard that increases pedestrian and vehicular safety, improves multimodal transportation options, increases community accessibility, and supports economic development on both sides of the Anacostia River.

 

I-295 / Malcolm X Avenue SE Interchange Improvement Project

The multiple phases of this project include the reconstruction of the I-295 interchange with Malcolm X Avenue SE, including modified ramps and a new access roadway to the St. Elizabeth’s West Campus. The planned improvements will be made between Firth Sterling Avenue SE, on the north, and the South Capitol Street/Martin Luther King, Jr. Avenue SE intersection to the south. The project will provide transportation improvements to serve the proposed Department of Homeland Security headquarters consolidation on the St. Elizabeth’s West Campus.

 

Traffic controls will be in place to guide all users of the roadway through the work zones safely. Motorists should expect delays due to the lane closures and are advised to stay alert and be observant of signage and road work crews while traveling in this area.
