Overview

The Silver line is the second addition beyond the originally envisioned 97 mile Metro system planned in the late 1960s. Like the Blue line extension to Largo Town Center, it was shown as a future line to Dulles International Airport on the planning maps. The 23 mile line branches from the Orange line roughly 1/2 mile east of the West Falls Church station, and runs through Tysons Corner, Reston and Herndon in Fairfax County and Dulles International Airport and beyond to Ashburn in Loudoun County.

The stations are radically different compared to the older surface and elevated station. No wayfinding pylons are found on the mezzanine and platforms. Pedestrian bridges connecting the entrances to the mezzanines feature poured in place concrete floors trimmed with red granite. Mezzanines feature red square concrete pavers trimmed with gray square concrete pavers. Platforms feature red concrete pavers that mimic the hexagon tile in the older stations. All station entrances are ADA accessible. Access between levels at the entrance and between the platforms and mezzanine feature two elevators and at least one escalator.

Unlike previous segments of the system, the Silver line was not built under the supervision of WMATA. Construction of the line was supervised by the Metropolitan Washington Airport Authority under the Virginia Public-Private Transportation Act.

$900 million of the $2.9 billion capital cost for the first phase was funded by the federal government. The remainder of the capital costs are being funded using revenue from the Dulles Toll Road and special taxing districts on commercial property. The second phase will be funded entirely with local funds from the Dulles Toll Road and special taxing districts.

Utility relocation and preparatory construction began in early 2008 with principle construction beginning in early 2009. The first phase of the Silver line opened from Largo Town Center to Wiehle - Reston East on July 26, 2014. The second phase of the project opened November 15, 2022.
