A new paving project has begun overnight on Interstate 95 in Maryland that is scheduled to continue of the next few weeks, weather permitting, which will include some triple lane closures overnights.

The Maryland Department of Transportation State Highway Administration is now working on the I-95/I-695 (Baltimore Beltway) interchange in Arbutus on a bridge rehabilitation project.

There will be installation of signs and work zone barriers, as well as a temporary traffic pattern change, as needed to prepare for the project to improve highway safety and ride quality on 10 bridges at the interchange.

During the overnight hours, motorists will encounter single, double and triple-lane closures on southbound I-95 at the interchange between 7 p.m. and 5 a.m. Traffic lanes on southbound I-95 will be shifted to the left and reflective barrels will be placed on the right to create a safe work zone.

Additional lane closures will take place from 7 p.m. Sunday, Sept. 18, to 5 a.m. Monday, Sept. 19, and Tuesday, Wednesday and Thursday, Sept. 20 to Sept. 22, through 5 a.m. the next day, overnight single- and double-lane closures will occur on northbound I-95.

This weekend has several events converging in the District on Sunday, starting with the DC Half Marathon, which will see street closures and parking restrictions between Rock Creek Park and Potomac Park.

There will also be the More Than Pink Walk with an opening set for 7 a.m. Sunday near Freedom Plaza then a walk toward the Capitol. There will also be a neighbor celebration and block party closing Upshur Street, NW for the Celebrate Petworth festival.

Be sure to check for any work associated with the I-295/DC-295 Corridor Project and the South Capitol Street Corridor Project. There are always various lane and ramp closures during off-peak times, including the weekends, between I-295 between Malcolm X Avenue and I-695, Firth Sterling, the Suitland Parkway as well as on South Capitol Street.

Metro has begun its fall shutdown with major construction on the Blue and Yellow lines, which closes six Yellow and Blue line stations south of Reagan National Airport. Service begins at 7 a.m. and closes at 1 a.m. on Saturday and on midnight Sunday.

Due to the rail service changes, Metro is providing more frequent weekend service on the Blue, Orange and Silver lines; and additional Green Line trains due to the loss of Yellow Line service.

During the construction on the Blue and Yellow lines, Metro will work to connect the future Potomac Yard Metrorail Station to the existing system, closing the Braddock Rd, King St-Old Town, Eisenhower Ave, Huntington, Van Dorn St and Franconia-Springfield stations for eight weeks. In addition, there will be no Yellow Line service for eight months due to the rehabilitation of the Yellow Line tunnel and bridge over the Potomac River.

Seven free shuttles will be offered during Phase One, including local and express shuttles in Virginia and three limited-stop shuttles crossing the Potomac River.

Local shuttles will be available during all Metrorail operating hours. For specifics on all shuttles and alternatives, check the Metro website.

Service impacts during Phase One, Sept. 10 to Oct. 22

(If 7000-series trains remain out of service, trains will operate less frequently, according to Metro.)

There will be additional maintenance on the Red Line, which requires single tracking between Forest Glen and Silver Spring. The full weekend schedule with service adjustments is available online.
