Headaches on the horizon

Construction of the Metrorail extension through Tysons Corner is closing the on-ramp from southbound Dolley Madison Boulevard (Route 123) to the eastbound Dulles Connector Road (Route 267) toward I-66 for about three months.

The closing, scheduled to start after tonight's rush hour, makes room for workers who will be building the supports for the elevated rail line near the Dulles Connector Road bridge across Route 123 in the McLean-Tysons Corner area.

Traffic using southbound Route 123 from the McLean area to reach eastbound I-66 and the Connector Road can use this detour to the eastbound Dulles Connector Road:
-- Continue south on Dolley Madison Boulevard (Route 123)
-- Turn left on Colshire Drive
-- Turn right on Colshire Meadow Drive
-- Turn right on Old Meadow Road
-- Turn right on to northbound Dolley Madison Boulevard (Route 123) to enter the ramp to eastbound Dulles Connector Road (Route 267 toward eastbound I-66).

Here's a project map showing the detour:
