The future Silver Line will be an extension of the Washington Metro subway system consisting of 29 subway stations from Route 772 in Loudoun County to Stadium-Armory in Washington, D.C. The line will have stations in Loudoun, Fairfax, and Arlington counties in Virginia, and the District of Columbia. Eighteen stations will be shared with the Orange Line, including all thirteen shared between the Orange and Blue Lines from Rosslyn to Stadium-Armory.

The Silver Line has two primary goals. The first, and most obvious, is to link the District of Columbia by rail to Dulles International Airport and the edge cities of Tysons Corner, Reston, Herndon, and Ashburn. The second goal is to spurn urban development in Tysons Corner and reduce overall reliance on vehicle traffic in Virginia's largest and the nation's 12th-largest business district. This will be a great challenge for an area that is comparable in size to downtown Washington, D.C., but is rather insulated from its surrounding neighborhoods and has no existing grid pattern in its streets.

History

The federal government – which, before Congress created the Metropolitan Washington Airports Authority, owned and operated Dulles Airport – built the Dulles Access Road in the 1960s to connect the airport to Washington by way of Interstate 66. The government opted, as the access road was built, to reserve the median of the road for some form of rail transit.^[1] Metropolitan Washington Airports Authority is an independant airport authority, created by the United States Congress to oversee management, operations, and capital development of Washington, D.C.s two major airports: Washington Reagan National Airport and Washington Dulles International Airport. ... Virginia Route 267 is composed of three sections, the Dulles Toll Road, the Dulles Greenway and the Dulles Airport Access Road. ...

Local residents and officials had talked of a Metro extension to Dulles since the Washington Metro began service in 1976, but a significant plan only developed in 2000. The Dulles Corridor Rapid Transit Project "scoping" process began in April 2000 with a series of meetings with local and federal officials, designed to collect the necessary authorities for the project. Local and federal law required extensive analysis of alternatives -- the two most likely being bus lanes or inaction -- and of the environmental impact. The rail-only line won over the other alternatives. Initial environmental hearings, which closed on August 28, 2002, were positive. The project received formal approval on June 10, 2004. Although construction was set to begin in 2005, delays in funding have pushed back the start date for construction to late 2007.

The extension will run in its own right-of-way on a route similar to that of the Dulles Access Road, running above ground both at grade and via aerial structure. The only significant diversions from the access road route are for the stops in Tysons Corner and at Dulles International Airport, where the Metro will alternate between subway and elevated track to maintain the exclusive right-of-way. A right-of-way (plural: rights-of-way) is an easement or strip of land granted to a railroad company upon which to build a railroad. ...

Service on the Silver Line is expected to begin in 2013^[2] between Wiehle Avenue and Stadium-Armory, with five new stations being added to the existing network west of East Falls Church. The full line to Route 772, including a station at Dulles International Airport, is expected to be completed in 2016.^[2] There will also be a provision made for a future in-fill station at Wolf Trap, between Wiehle Avenue and Tysons West.

Controversies

There has been controversy over the contract between the Metropolitan Washington Airports Authority and the contractor, Dulles Transit Partners, which consists of Bechtel and Washington Group International. As part of the Virginia Public-Private Partnership, this $2,700,000,000 project has not been bid out, and there is no upper cap on its cost. The state has refused to make details of the contract publicly available.^[3] The method of construction through the Tysons Corner area generated much debate. In the end, however, plans were made to build the extension above ground. Early plans called for a tunnel running from before Tysons East to beyond Tysons West with all four stations in between being below ground. When the contractor hired to design the Silver Line—a consortium of Bechtel and Washington Group International—found the costs to be too high, the design was changed to use a short tunnel between Tysons 123 and Tysons 7 stations with all four stations being at or above ground.^[4] In March 2006, the contractor was ordered to examine an alternative tunnel digging technique with the potential to lower costs. The contractor found that there would not be a significant cost reduction and proposed staying with the longer tunnel option.^[5] In April 2006, the long tunnel concept was revived after allegations that the design contractor had inflated costs for the tunnel in order to avoid sharing the job with an outside tunneling contractor. The allegations led to calls for an outside cost estimate to determine more realistic tunnel costs.^[6] Metropolitan Washington Airports Authority is an independant airport authority, created by the United States Congress to oversee management, operations, and capital development of Washington, D.C.s two major airports: Washington Reagan National Airport and Washington Dulles International Airport. ...

On May 15, 2006, Virginia Transportation Secretary Pierce R. Homer announced the creation of an advisory panel headed by the American Society of Civil Engineers. The panel had about two months to evaluate options for completing the line through Tysons Corner,^[7] with the results presented to the state on July 27, 2006^[8] and published on July 31, 2006.^[9] On September 6, 2006, Virginia Governor Tim Kaine announced his decision in favor of an elevated track through Tysons Corner. In his statement, Kaine said he believed a tunnel would be the best option, but decided against it, citing a fear of losing federal funding for the project.^[2] However, Virginia has until May 2008 to submit their final proposal to the FTA.^[10] is the 135th day of the year (136th in leap years) in the Gregorian calendar. ...

The tunnel controversy, however, is not over. Shortly after Governor Kaine's decision, the Greater McLean Chamber of Commerce formed a coalition of tunnel supporters and put forth a technical proposal to help revive consideration of building a tunnel through Tysons Corner.^[11] The Virginia Department of Rail and Public Transportation hired an independent consultant to assess the coalition's proposal. The consultant's report—sent on March 7, 2007, to Secretary Homer—stated, however, that "[t]here is a significant risk that the project cost of a Large Bore Tunnel would not meet the Federal Transit Administration’s Cost Effectiveness ratio criteria, which could compromise federal funding for the project."^[12][13] Boundaries of the McLean CDP as of 2003. ...
