South Capitol Street Corridor

Project Overview

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

Preliminary engineering and Right of Way land acquisition for the project have been underway since January 2012. In June 2013, DDOT issued a Request for Qualifications (RFQ) from contractors for design-build construction of the first phase of the project. DDOT evaluated submitted Statements of Qualification from the proposer teams and notified four short-listed contractor teams in January 2014 of their advancement to the second stage of the procurement process with an opportunity to respond to a detailed Request for Proposals (RFP).

On August 13, 2015 the Federal Highway Administration (FHWA) approved the Supplemental Final Environmental Impact Statement (SFEIS) and issued a Record of Decision (ROD) for the South Capitol Street Corridor Project—both indicating federal approval of the project.

Key project elements include:

  • Building a new six-lane Frederick Douglass Memorial Bridge;
  • Creating a new traffic oval west of the river that connects South Capitol Street, Potomac Avenue and Q Street SW;
  • Reconstructing South Capitol Street as a six-lane boulevard with an improved streetscape from the traffic oval to D Street SE/SW and an at-grade intersection at M Street SE;
  • Creating a new at-grade traffic oval east of the river that connects South Capitol Street, Suitland Parkway and Howard Road SE;
  • Reconstructing the Suitland Parkway/Interstate 295 interchange;
  • Constructing a new diamond interchange on Suitland Parkway at Martin Luther King Jr Avenue;
  • Improving related portions of New Jersey Avenue, Howard Road, Firth Sterling Avenue, and Sheridan Road SE;
  • Increasing bicycle and pedestrian facilities; and
  • Improving drainage and storm water management throughout the corridor.

Project Segments

To best manage financing costs and potential construction impacts, DDOT has divided the project into five segments that are to be designed and constructed in two phases.

Phase 1 includes Segments 1 and 2. Segment 1 consists of replacing the existing Frederick Douglass Memorial Bridge and its approaches with a new bridge and approaches, including also the demolition of the old Frederick Douglass Memorial Bridge. Segment 2 consists of constructing a new Suitland Parkway/I-295 Interchange.  Phase 2 includes the three remaining segments that are to be advanced in future years.
