Weekend road and rail: Work on Beltway ramp to I-66, paving on I-270 and Metro trackwork

This weekend will see the Outer Loop ramp to go westbound on Interstate 66 closed and detoured during the overnight hours. In the District, Interstate 395 northbound over the Case Bridge will see overnight work stopping all traffic in 30-minute increments, plus closures again on the Suitland Parkway.

In Maryland, a big paving project begins on Interstate 270.

Metro riders should be prepared for some disruptions, too.

Here’s everything you need to know about getting around this weekend.



The Capital Beltway Outer Loop lane closures are set to continue over the Northwest Branch Bridge between MD-650/New Hampshire Ave and MD-193/University Boulevard in Montgomery County.

The Maryland Department of Transportation State Highway Administration is continuing its long-term work, which will have intermittent closures of one, two and three lanes during off-peak hours.

The project, which was originally slated for completion in the summer, is now looking to continue through the end of the year, weather permitting.

For the weekend, scheduled repairs will run from 9 p.m. Friday through 5 a.m. Monday.

During these work times there will be signs to alert drivers of the changing traffic patterns. Motorists should expect delays, add extra commute time and use alternate routes during the repairs. There will be additional work times and lane closures possible to complete this work.

In Frederick, crews begin pavement repairs to I-270 southbound between MD-85/Buckeystown Pike and MD-80/Fingerboard Road and I-270 northbound between MD-80 and the Montgomery County line just north of MD-109 Old Hundred Road.

The crews will start on the southbound lanes of I-270 nightly between 7 p.m. Sundays through 4 a.m. Fridays. Once they’ve completed the southbound, they will begin work northbound, between 9 p.m. and 5 a.m. Sunday through Friday.

The $340,000 project is expected to be completed by December requiring single lane closures during working hours.

In Anne Arundel County, pavement repairs have begun on I-97 in both directions between MD-3 and MD-174. Motorists can expect lane shifts from 9 p.m. to 5 a.m., Sunday through Thursday, with single lane closures between 9 a.m. to 3 p.m. Monday through Friday.

The District Department of Transportation plans to temporarily stop all traffic on I-395 northbound just before the 12th Street Expressway/Capital One Arena exit 3.

Beginning Friday around 11 p.m., the work area will reduce travel to one lane, followed by 30-minute full stoppages between the Potomac Park/U.S. Park Police exit 2 and the 12th Street Expressway ramp, which is the Case Bridge over the Southwest Waterfront.

During this time, the following ramps will be closed:

Throughout this week, the work continued in the overnight hours with closures on the Suitland Parkway.

DDOT reports they will be continuing this work into Saturday. The overnight work, between 8 p.m. through 5 a.m., closes the Suitland Parkway between South Capitol Street and Firth Sterling Avenue, SE, which means no access to I-295/Suitland Parkway interchange.

This Saturday, the work is scheduled to continue through 9 p.m. with detours in place to help motorists navigate the closure. In the event of an unforeseen delay, or bad weather, the Saturday closure will be pushed to Sunday.

In addition, there has also been a nightly closures of Howard Rd underneath of I-295, which has been in place every night since Monday between Firth Sterling Avenue, SE and the WMATA parking garage.
