Half a century ago, when Dulles International Airport was constructed in the farmlands of Virginia, planners were forming a blueprint for the Washington region’s new Metro system. Back then, they ruled out the idea of stretching the rail line 30 miles beyond the capital through rural counties to connect with the airport. Such a line would serve no purpose for commuters, they said, and would do nothing to help congestion.
But there wasn’t a total absence of foresight regarding the region’s potential explosion. Along with the airport came the Dulles Access Road — and through the center of it, a median reserved for future transit.
The new Silver Line, which officially opened to riders on Saturday after months of delays, runs along that exact path. Ultimately, the 23-mile extension — the largest infrastructure project in the nation – will connect not only to the airport but beyond it to Ashburn, Virginia. The $2.9 billion first phase laid 11.7 miles of new track along five new stations in Tysons Corner and Reston, expanding the Metro system’s mileage by 10 percent.
Today is the first weekday for commuters to try out the new line, which runs east from Reston through the city to Largo Town Center in Maryland. WMATA predicts ridership will be low at first, then eventually reach as many as 25,000 boardings a day. As of 10 a.m. today, more than 9,500 people had passed through the five new stations, the agency said.
It took over five decades for the Silver Line to get here. The last 20 years were particularly contentious, as the project overcame political strife, cost overruns, financing complexities, and construction delays.
