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 ends of the Anacostia River.

While preliminary engineering and right-of-way land acquisition for the project have been underway since January 2012, final federal environmental approval and construction funding are still pending. The District Department of Transportation (DDOT) anticipates procuring a design-build contract for constructing initial phases of the project in 2015.

On June 13, 2013, DDOT issued a Request for Qualifications (RFQ) from contractors for design-build construction of Segments 1 and 2. This was the first step of a two step procurement process for the project. DDOT evaluated Statements of Qualification from proposer teams and notified four short-listed contractor teams of their advancement to the second phase of the procurement with an opportunity to respond to a detailed Request for Proposals (RFP).

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 ant 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.

Estimated to cost about $608 million, Phase 1 includes Segments 1 and 2. Segment 1 consists of replacing the existing Frederick Douglas Memorial Bridge and its approaches with a new bridge and approaches. 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 at total cost of about $300 million.
