Complete closure of northbound Route 123 in McLean/Tysons coming March 5

All northbound lanes of Route 123 near the Dulles Connector Road (Route 267) between McLean and Tysons Corner will be shut down for 14 hours beginning 8 p.m. Friday, March 5. The lanes will reopen by 10 a.m. Saturday, March 6. Staging for the closing will begin at 7 p.m.

All northbound thru traffic from the Tysons Corner area toward McLean and the Chain Bridge will be detoured for less than a mile. Signs will direct drivers to turn right on Anderson Road, left on Old Chain Bridge Road, left on to Great Falls Street, then right on northbound Route 123.

The ramp leading from northbound Route 123, just north of Anderson Road, to eastbound I-66 via the Dulles Connector Road will remain open. In addition, the ramp from the eastbound Dulles Toll Road/Dulles Connector Road to northbound Route 123 will be open.

Residents of the communities along Anderson and Old Chain Bridge Road and Great Falls Street should be alert for additional traffic during the closing of northbound Route 123.

Also, eastbound Dulles Toll Road/Dulles Connector Road drivers from Dulles Airport and the Reston area who use the southbound 123 exit ramp to cross Route 123 to Anderson Road/Old Chain Bridge Road will experience additional traffic on those roads. Police officers will be in place along the detour route to direct motorists. Drivers are also urged to pay close attention to signage and to be extremely careful in this area. Electronic signage warning of the closings will be in place along Route 123 prior to the closing and detour.

The closing is necessary for the relocation of a water line. It is part of the construction of the Dulles Corridor Metrorail Project.
Water service to residents and businesses in the area should not be affected.

All work is weather permitting and subject to change. For construction-related emergencies, call the Project Hotline at 877-585-6789. For information about the project, visit www.dullesmetro.com or call 703-572-0506.
