Before you head out on your commute or summer vacation, take a glance at what construction, delays and detours you might face this week.

Weather permitting, crews expect to implement the following full closures and detours of both the eastbound Dulles International Airport Access Highway (DIAAH) and Dulles Toll Road (Route 267) on Monday and Tuesday nights. The entrance ramp from eastbound Leesburg Pike (Route 7) to the eastbound Dulles Toll Road (Route 267) also will be closed.

• 7:30 p.m.: The right lane of the eastbound DIAAH also will close near Route 7.
• 8 p.m.:All eastbound DIAAH traffic will be diverted on to the single westbound lane, which will remain open to accommodate diverted Toll Road traffic (see listing below). At this time, westbound DIAAH will be two-way traffic.

Closures will be picked up in reverse order, to be completed at 5 a.m. the following mornings to avoid the morning rush hour.

Bridge Construction over Westpark Drive/Gosnell Road at Leesburg Pike (Route 7); Multiple Overnight Closures and Detours Required
 
Cranes are constructing bridge segments over the Westpark Drive/Gosnell Road intersection with Leesburg Pike (Route 7).
 
Overnight thru traffic along both directions of Leesburg Pike (Route 7) still will be open, but left turns on to Westpark or Gosnell will not be allowed. For safety reasons, thru traffic on Westpark/Gosnell will be prohibited, and will be detoured by using Route 7 as follows:
Southbound Westpark Drive thru traffic and motorists wanting to turn left on to eastbound Leesburg Pike will need to turn right on to westbound Leesburg Pike, then U-turn at either Spring Hill Road or Tyco Road, and continue on eastbound Leesburg Pike towards Gosnell Road.
Northbound Gosnell Road thru traffic and motorists wanting to turn left on to westbound Leesburg Pike will need to turn right on to eastbound Leesburg Pike, pass under Route 123, turn left on International Drive, left on Chain Bridge Road (Route 123), then take the exit ramp to Route 7 to turn right on Westpark Drive.
 Weather permitting, these closures take place from 11 p.m. to 5 a.m. Sundays through Fridays for approximately the next five to six weeks.
