Dulles Metrorail - About Dulles Metrorail

Dulles Metrorail Project Overview

The Metropolitan Washington Airports Authority (MWAA) is constructing a 23-mile extension of the existing Metrorail system, which will be operated by the Washington Metropolitan Area Transit Authority (WMATA) from East Falls Church to Washington Dulles International Airport west to Ashburn.

The extension will serve Tysons Corner, Virginia's largest employment center, and the Reston/Herndon area, the state's second largest employment concentration. And, it will provide a one-seat ride from Dulles International Airport to downtown Washington. It will be called the Silver Line.

Phase 1 and 2

The project will include 11 new stations. It will be built in two phases. Phase 1 will run from East Falls Church to Wiehle Avenue on the eastern edge of Reston. It will include four stations in Tysons Corner-McLean, Tysons Corner, Greensboro and Spring Hill and Wiehle-Reston East station, located at Wiehle Avenue in Reston. Construction began in March of 2009 and it will be completed in early 2014, then transferred to WMATA. The opening date will be scheduled by WMATA and is anticipated to take place in 2014.

Phase 2 will run from Wiehle Avenue to Ashburn in eastern Loudoun County. On May 14, 2013 the Metropolitan Washington Airports Authority awarded Capital Rail Constructors the major design-build portion of Phase 2 of the Dulles Corridor Metrorail Project. On July 9, 2013, the Metropolitan Washington Airports Authority issued a Notice of Proceed to Capital Rail Constructors, a joint venture of Clark Construction Group and Kiewit Infrastructure South, to begin construction of Phase 2. Preliminary geotech work began in the last quarter of 2013, and heavy construction is anticipated to begin in Spring/Summer 2014. Phase 2 will Reston Town Center, Herndon, Washington Dulles International Airport, Route 606 and Ashburn.

The Silver Line will provide high-quality, high-capacity transit service in the Dulles Corridor. The new Metrorail service will help mitigate traffic congestion, expand the reach of the existing regional rail system, offer a viable alternative to automobile travel and support future transit-oriented development along the corridor.

MWAA and the Phase 1 contractor Dulles Transit Partners

MWAA and Dulles Transit Partners in March 2008 signed an updated $1.6 billion fixed-price contract to build the project, keeping the costs of the project to $2.6 billion.

Utility Relocation

The construction team relocated of 21 different utilities in the Tysons Corner area prior to the start of project construction. That work was done primarily in the busy Route 7 corridor between Route 123 and the Dulles Toll Road but some work took place in along Route 123.

Early Decisions

A Draft Environmental Impact Statement (Draft EIS) for the project was completed in June 2002. This Draft EIS evaluated several alternatives, including three Bus Rapid Transit (BRT) options, a combined BRT/Metrorail alternative and a full Metrorail extension. Public hearings on the Draft EIS were held in July 2002. Based on extensive public comments and input from local jurisdictions, the full extension of Metrorail was recommended as preferred option or Locally Preferred Alternative (LPA).

This Dulles Metrorail project was approved by the WMATA Board of Directors in November 2002 and the Commonwealth Transportation Board (CTB) in December 2002. The project was also endorsed by the Fairfax County, Loudoun County and MWAA Boards.

Following these approvals, a Final EIS was published in December 2004 and the FTA issued its Record of Decision approving the environmental process in March 2005.
