The Dulles Corridor Metrorail Project, informally dubbed the Silver Line due to its color on maps, is a planned extension of the Washington Metro rapid transit system, consisting of 29 stations from Route 772 in Loudoun County, Virginia to Stadium-Armory in Washington, D.C., United States. A third rail is a method of providing Electricity to power a railway through a continuous rigid conductor alongside the railway track or between the rails The Red Line of the Washington Metro is a rail Rapid transit service operating between 27 stations in Montgomery County, Maryland The Orange Line of the Washington Metro consists of 26 Rapid transit stations from Vienna/Fairfax-GMU to New Carrollton. The Blue Line of the Washington Metro consists of 27 Rapid transit stations from Franconia-Springfield to Largo Town Center. The Yellow Line of the Washington Metro consists of twelve Rapid transit stations from Huntington to Mt Vernon Sq/7th St-Convention The Green Line of the Washington Metro consists of 21 Rapid transit stations from Branch Avenue to Greenbelt.

The Silver Line has two primary goals. The first is to link the District of Columbia by rail to Washington Dulles International Airport and the edge cities of Tysons Corner, Reston, Herndon, and Ashburn. Washington DC ( formally the District of Columbia and commonly referred to as Washington, the District, or simply D Washington Dulles International Airport is a public Airport located 25 miles (40 km) west of the Central business district of Washington D Edge city is an American term for a relatively new concentration of business shopping and entertainment outside a traditional Urban area in what had recently been Tysons Corner is an Unincorporated area in Fairfax County, Virginia, near Washington D Reston is an internationally known Planned community whose goal was to revolutionize post-World War II concepts of land use and residential/corporate development in Herndon is a town in Fairfax County, Virginia, United States. Ashburn Virginia is an unincorporated area located in Loudoun County, Virginia, 30 miles west of Washington D The second is to spur urban development in Tysons Corner and reduce overall reliance on vehicle traffic in the business district, Virginia's largest and the 12th-largest in the nation. 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.
Unlike all prior segments of the Metrorail system, which were designed and constructed by the Washington Metropolitan Area Transportation Authority (WMATA), this line will be designed and constructed by the Metropolitan Washington Airports Authority and operated by WMATA. The Washington Metropolitan Area Transit Authority ( WMATA) is a tri-jurisdictional Government agency authorized by Congress, that operates transit Metropolitan Washington Airports Authority is an independent Airport authority, created by the United States Congress to oversee management operations and capital The first phase of the project is funded 43% by $900 million of federal funding, 28% by a special tax district on commercial property proximate to the Silver Line route, and 28% by a $0. 50 toll increase on the Dulles Toll Road. State Route 267 is a primary State highway in the US state of Virginia.  Funding for the second phase of the project will be shared by Loudoun County, Fairfax County, the commonwealth of Virginia, and the Metropolitan Washington Airports Authority. Metropolitan Washington Airports Authority is an independent Airport authority, created by the United States Congress to oversee management operations and capital 
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. State Route 267 is a primary State highway in the US state of Virginia. The 1960s decade refers to the years from the beginning of 1960 to the end of 1969 Interstate 66 (I-66 is an Interstate highway in the eastern United States. The government opted, as the access road was built, to reserve the median of the road for some form of rail transit.

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. Year 1976 ( MCMLXXVI) was a Leap year starting on Thursday (link will display full calendar of the Gregorian calendar. 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 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. A right-of-way is a strip of land that is granted – through an Easement or other mechanism – for Transportation purposes such as for a Rail line or 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.
Service on the Silver Line is expected to begin in 2013 between Wiehle Avenue and Stadium-Armory, with five new stations being added to the existing network west of East Falls Church. 2013 ( MMXIII) will be a Common year starting on Tuesday of the Gregorian calendar. Wiehle Avenue is a planned Washington Metro station in Fairfax County, Virginia on the Silver Line. Stadium-Armory is a Washington Metro station in Washington DC East Falls Church is a Washington Metro station in Arlington, Virginia on the Orange Line. The full line to Route 772, including a station at Dulles International Airport, is expected to be completed in 2016. Route 772/Ryan Road is a planned Washington Metro station in Loudoun County, Virginia, United States, on the Silver Line  There will also be a provision made for a future in-fill station at Wolf Trap, between Wiehle Avenue and Tysons West. Wiehle Avenue is a planned Washington Metro station in Fairfax County, Virginia on the Silver Line. Tysons West is a planned Washington Metro station in Fairfax County, Virginia, on the Silver Line.
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. Metropolitan Washington Airports Authority is an independent Airport authority, created by the United States Congress to oversee management operations and capital Bechtel Corporation ( Bechtel Group) is the largest Engineering company in the United States, ranking as the 9th-largest privately owned company in the Washington Group International was an American corporation which provided integrated engineering construction and management services to businesses and governments around the world 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.  The contract provides for price escalation of $3 million to $6 million a month for delays. 
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 only between Tysons 123 and Tysons 7 stations (underneath higher ground)with all four stations being at or above ground. Bechtel Corporation ( Bechtel Group) is the largest Engineering company in the United States, ranking as the 9th-largest privately owned company in the Washington Group International was an American corporation which provided integrated engineering construction and management services to businesses and governments around the world  In March 2006, the contractor was ordered to examine an alternative "large bore" tunnel digging technique (successfully used in Europe) with the potential to lower costs of a tunnel through the entire Tysons section. The contractor found that there would not be a significant cost reduction and proposed staying with the short tunnel option.  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.

The Governor of Virginia serves as the chief executive of the Commonwealth of Virginia for a four-year term Timothy Michael "Tim" Kaine (born February 26, 1958) is an American politician and the current Governor of Virginia. 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.  However, Virginia has until May 2008 to submit their final proposal to the Federal Transit Administration (FTA). The Federal Transit Administration ( FTA) is an agency within the United States Department of Transportation (DOT that provides financial and technical assistance 
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. McLean (pronounced "mick-CLANE") is an Unincorporated community located in Fairfax County in Northern Virginia. A chamber of commerce (also referred to in some circles as a board of trade) is a form of Business network.  The Virginia Department of Rail and Public Transportation hired an independent consultant to assess the coalition's proposal. Virginia Department of Rail and Public Transportation (VDRPT is an agency of the Commonwealth of Virginia in the United States. 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 FTA's cost effectiveness ratio criteria, which could compromise federal funding for the project.

FTA Administrator James Simpson presented Governor Kaine with a letter which included stark criticisms with the project as presented. The project as presented was given a "Medium-Low" rating (projects must receive a "Medium" or higher rating to be approved under the Federal New Starts Funds project) and was ineligible to receive the $900 million in federal funding. FTA's concerns included the Metropolitan Washington Airports Authority's inexperience in large design-build contracts, an exaggeration of funding numbers from the Dulles Toll Road, and an inability for Metro to maintain the 23 mile line once it had been built. State Route 267 is a primary State highway in the US state of Virginia.
