Weekend road and rail: Work on I-66, bridge work on Capital Beltway, 3 Metrorail stations closed

From bridge work to sign work to Metro maintenance, here is what you need to know about getting around the D.C. area this weekend.



This weekend will see sweeping and maintenance during the day, with moving, single lane closures on Interstate 66, anywhere between Gainesville and the Capital Beltway between the hours of 9 a.m. and 1 p.m.

There will be ongoing Transform I-66 projects, continuing as they have all week. Overnight Friday before and after Route 123, the demolition of the old Route 123 bridge over I-66 continues.

In both directions of I-66, between 9 p.m. and 9 a.m., travel will be reduced to a single lane. And, from midnight to 4 a.m. nightly, motorists can expect periodic stops of up to 20 minutes at a time.

There is also continuing work at the Gallows Road bridge over I-66, just west of the Capital Beltway, where overnight through Saturday morning, travel is being reduced to a single lane, with stops of up to 20 minutes at a time between 11 p.m. and 4 a.m. nightly.

With this work, the ramps from Interstate 495 Express Lanes north to westbound I-66 will be closed and detoured east, toward Route 7 to make a U-turn. Gallows Road over I-66 will also be reduced to a single lane of travel both ways.

The transformation work is also continuing at the Stringfellow Road-I-66 interchange, with travel overnights being reduced to a single lane.

In Centreville, sometime in the early morning hours of Saturday, the ramp from Route 29/Lee Highway northbound to I-66 east will be closing for about four months.

On northbound Route 29, the left-turn lane and ramp eastbound I-66 will be directed to continue north to for U-turns at Trinity Parkway/Machen Road. As an alternate, motorists could continue north to Route 28 north to following signs to I-66 East.

The closure is needed for Transform 66 Outside the Beltway Project construction that will widen, lengthen, and raise the I-66 bridges over Route 29 to accommodate future transportation improvements at the Route 29 interchange.
