Weekend Road and Rail: Metro gives riders a break; Suitland Parkway closures

This weekend will see a rare break from track work on Metro, with all stations open and trains operating on normal weekend schedules.

Overnight closures continue on Interstate 66 in Virginia, with scheduled interchange work at Routes 29 and 28 in Centreville. Bridge work is scheduled in Maryland on the Capitol Beltway and MD-450/Defense Highway. The I-295/DC-295 rehabilitation project continues with lanes and ramp closures, and a full closure of the Suitland Parkway.

Here’s what you need to know.



It may be cold, but weather-dependent I-66 work will be continuing into the weekend. Motorists on I-66 overnights near the U.S. Route 50 interchange have seen overnight detours for an ongoing bridge installation project, as part of the ongoing, ever-changing I-66 Transforms Outside the Beltway Project.

This particular I-66/U.S. 50 Interchange is being rebuilt to add Express Lane access to and from the east and to construct a new, shared-use path.

In Fairfax overnights, I-66 westbound at the Route 50 interchange has been closed and detoured using Route 50 and West Ox Road with the westbound ramps to/from Route 50 closed.

Those moving eastbound on Route 50 from West Ox toward I-66 have travel reduced to a single lane with full stops of up to 20 minutes at a time. All work, scheduled nightly, will continue into Sunday morning between 10:30 p.m. and 5:30 a.m. This work is scheduled overnights through Wednesday.

Farther east along I-66, all lanes approaching Route 123/Chain Bridge Road continue to close nightly for continued demolition of the old Route 123 bridges.

During this overnight work, all traffic on I-66 is detoured around the closure using the ramps at the Route 123 interchange. Route 123 remains open during these operations, but drivers should expect possible delays crossing over I-66 and follow police direction.

This weekend’s closures for I-66 at Route 123 will continue nightly between 10:30 p.m. and 7 a.m. Saturday and Sunday, and through 5 a.m. Monday.

In Centreville, bridge demolition continues at the I-66/Route 29 Lee Highway interchange with northbound Route 29 being reduce to a single travel lane under the interstate. This overnight work sees all lanes reopening by 5 a.m.

There is work nightly at the Route 28/I-66 interchange, which too will continue into Saturday morning. Motorists should expect to see overnight ramp and lane closures on Route 28 at I-66 with Braddock Road eastbound closing and detouring at Newton Patent Drive.

Overnight work will see crews implementing a traffic shift of Route 28 in preparation for the demolition of the old Route 28 southbound bridge over I-66. During this time, Route 28 south is reduced to a single lane between 9 p.m. and 5 a.m. with Braddock Road directed to Westfields Boulevard.

The ramp from I-66 westbound to Route 28 south is closed nightly starting on or about 11 p.m. with traffic detoured to the next exit for Route 29/Lee Highway to head north for a U-turn. The ramp from Route 28 south to I-66 east will be closed with a posted detour too.

In Leesburg this weekend, overnight roadwork is scheduled for eastbound Route 7/East Market Street between the Leesburg Bypass (Route 7/Route 15) and River Creek Parkway as part of the Route 7/Battlefield Parkway Project.

At least one eastbound lane of Route 7 remains open at all times. Message boards displaying the lane closure information will be in place as part of advance notification for travelers.
