Update: Monday Night Closings Cancelled, Will Resume Tuesday

Up to 30 minute closings of the Beltway in two locations this week

Update: Monday night closings have been cancelled.

Here is this week's list of traffic tangles  brought to you by the simultaneous construction of the new subway line to Reston and the express (aka HOT) lanes through the McLean-Tysons Corner area.

Dulles International Airport Access Hwy. west at I-495 - Road close Monday-Thursday nights for bridge overhang work. Traffic will be directed to use the Dulles Connector Rd. (Route 267) west. Motorists will not be tolled.

I-495 north from Chain Bridge Rd. (Route 123) to Dulles Connector Rd. (Route 267) - Three lanes closed Tuesday night for overhead sign installation. Expect intermittent full road closures of up to 30 minutes after midnight.

I-495 north to Exit 47A and B, Leesburg Pike (Route 7) west and east - Ramp closed Friday and Saturday nights for traffic shift. Traffic will be directed to continue north to Exit 46A, Chain Bridge Rd. (Route 123) south, stay to the right, follow signs to I-495 south and take Exit 47A or B, Leesburg Pike (Route 7) west or east.

I-495 north from Oak St. overpass to Exit 47, Leesburg Pike (Route 7) - Three left lanes closed Monday - Saturday nights for traffic shift. Expect intermittent full road closures of up to 30 minutes after midnight

Temporary Road Shift of Eastbound Leesburg Pike (Route 7) near Dulles Toll Road (Route 267) to Be Implemented Overnight Thursday, March 8; Exit Ramp from Eastbound Access Highway to Westbound Route 7 to Close
Construction of the bridge in the median of Leesburg Pike (Route 7) in Tysons Corner is about to begin the final stretch of this guideway - the flyover between Route 7 and the median of the Dulles International Airport Access Highway (DIAAH). The large yellow and blue truss constructing this guideway first must cross over the lanes of eastbound Route 7.
Road Shift
Crews will implement a temporary shift of the eastbound lanes approximately 30 feet to the right so bridge construction can continue, and avoid working over an active roadway.
This temporary lane shift is expected to be implemented in the overnight hours Thursday, March 8 as follows:
9 p.m. to midnight - Right thru lane closed from Jarrett Valley Drive to the exit ramp from the eastbound DIAAH
Midnight to 5 a.m. - Left thru lane closed in same area
Brief, 15-minute maximum total closures of eastbound Route 7 may be required for the traffic switch.
Ramp Closure and Detour
In addition, the ramp from the eastbound DIAAH to westbound Route 7 will be closed, beginning overnight Thursday, March 8.
Ramp detour: To access westbound Route 7 from the eastbound DIAAH, drivers should use the exit from the eastbound DIAAH to eastbound Route 7 instead, then U-turn at Spring Hill Road on to westbound Route 7.
This shift and ramp closure will be in place for approximately two weeks. Then, the eastbound lanes of Route 7 will shift back to the current configuration, and the ramp will reopen as the truss moves westward. This plan eliminates the need for full overnight closures of eastbound Route 7.
Eastbound Tysons Boulevard to Close Sunday through Friday Nights
The eastbound lanes of Tysons Boulevard will be closed between Chain Bridge Road (Route 123) and Galleria Drive Sunday through Friday nights, March 4-9, for overhead bridge, pier and station work near the future Tysons Central 123 station.
This also will require the closures of the turn lanes on to eastbound Tysons Boulevard from northbound Chain Bridge Road (Route 123), and northbound and southbound Galleria Drive. Generally, these lane closures will begin to be implemented at 9:30 p.m. each night, and will be lifted between 5 a.m. each following morning.
Detours around this closure will be in place. Please use extreme caution, pay attention to signage, and obey police direction if traveling around this intersection.

Galleria Dr. west at Tysons Blvd. - Three left turn lanes closed Sunday - Friday nights for span work. Traffic will be directed to follow posted detour signs.
