The ramp from westbound Leesburg Pike (Route 7) to the eastbound Dulles Toll Road (Route 267) toward D.C. will be closed overnights tonight through Thursday, if weather permits. A chance of thunderstorms is in the forecast each day.

Crews will be paving and striping the road in that area. A slight shift of the westbound Route 7 lanes should be in place by Friday morning.

If the work, which is part of the Dulles Metrorail project, goes ahead on schedule, the ramp will be closed from 11 p.m.each night through 5 a.m. the next morning.

To reach the eastbound Dulles Toll Road, westbound Route 7 traffic will be directed to turn right on Tyco Road, left on Spring Hill Road, make a slight left again at the Spring Hill/International Drive/Jones Branch Drive intersection, then make an immediate right onto the Toll Road ramp.
