McLEAN, Va. (AP) -- The Metropolitan Washington Airports Authority is again pushing back its expected completion date for construction of the new Silver Line through Tysons Corner.
The airports authority, which oversees construction of the new commuter line, says it needs several more weeks to complete work. Its most recent estimate had been that it would finish up at the end of November.
Because the Washington Metropolitan Area Transit Authority, which operates Metrorail, estimates it will need 90 days to conduct its own tests, passengers are unlikely to ride the line until the end of March.
This is the second announced delay; the initial estimate had been that passengers would be riding the Silver Line by the end of 2013.
The airports authority wants to run more tests on its automated train-control software.
