The District Department of Transportation (DDOT) and the Federal Highway Administration (FHWA) are preparing an Environmental Assessment (EA) for proposed modifications to the transportation infrastructure between 2nd Street, 3rd Street, D Street, and H Street, NW in downtown Washington DC. The EA is being prepared in accordance with the National Environmental Policy Act of 1969 (NEPA), the Council of Environmental Quality (CEQ) regulations (40 CFR 1500-1508), and the FHWA's Environmental Impact and Related Procedures (23 CFR 771).

DDOT and FHWA are also reviewing the potential effects of the proposed project on historic properties, consistent with Section 106 of the National Historic Preservation Act.

The purpose and need for the project is to

  • Maintain or enhance the functionality of the local and regional transportation system and reestablish historic surface connections
  • Create room for seamless, economically and environmentally sustainable air-right development over I-395 (Center Leg Freeway).
