Sunrise Valley Drive was closed yesterday (Tuesday) near the Herndon-Monroe Park and Ride garage, causing major back-ups in both directions.
The Metropolitan Washington Airports Authority says a construction excavator hit a gas line and caused major back-ups in the area. The incident happened yesterday afternoon.
Crews worked last night to install a temporary fix to reopen the eastbound lanes. The accident also caused delays on the Fairfax Connector.
All service has resumed to normal.
