Update: Major Overnight Closings of the Beltway at Rte 66

URGENT: Ramp from Westbound Route 7 to Eastbound Dulles Toll Road Closing Tonight.

The on-ramp from westbound Leesburg Pike (Route 7) to the eastbound Dulles Toll Road (Route 267) toward Washington will be closed overnights starting tonight,  through Thursday, May 26, between 11 p.m. and 5 a.m., for Dulles Corridor Metrorail Project construction.
 
To access the eastbound Dulles Toll Road, westbound Route 7 traffic will be directed to turn right on Tyco Road, left on Spring Hill Road, a slight left again at the Spring Hill/International Drive/Jones Branch Drive intersection, then an immediate right on to the Toll Road on-ramp.
 
Crews will be paving and striping the road in that area with a slight lane shift of westbound Route 7 expected to be in place by Friday morning.

I-495 south at I-66 Lane Closings.

 Tuesday, May 24 through Thursday, May 26, starting at 9:30 p.m. one lane will close on I-495 (the Capital Beltway)  south at I-66, progressing to a full I-495 south closure after 11 p.m. for steel beam placement. The I-66 westbound ramp to I-495 south and the left I-66 eastbound HOV ramp to I-495 south/north will also be closed.  Motorists will be detoured from I-495 south to I-66 west, to Exit 62, Nutley Street and follow signage to I-66 east back to I-495 south.  The detour may add an additional 15-20 minutes onto a trip during the peak overnight hours. All lanes will reopen by 5 a.m.

I-66 Westbound Detour Overnights May 23-24

 Interstate 66 westbound at the Dulles Connector Road (Route 267) will be closed overnight Monday, May 23 and Tuesday, May 24, between 11 p.m. and 5 a.m., for Dulles Corridor Metrorail Project construction weather permitting.
 
These closures will affect drivers bound for destinations along I-66 west of Arlington.vThru traffic will be detoured on to the Dulles Connector Road westbound, then on to the Capital Beltway north, to a U-turn at Georgetown Pike to go south on the beltway. Drivers can then rejoin I-66 from the beltway.
 
To avoid the closure, drivers bound for destinations inside the Capital Beltway may find alternate routes via other local westbound roads by exiting I-66 prior to the I-66/Dulles Connector Road split. For example, traffic bound for the Falls Church City/Broad Street and Idylwood areas can exit before the detour and use Route 29/Washington Street to connect with Broad Street (Route 7 west).
