Marine Corps Marathon

Many roads on both sides of the Potomac River in the District and Arlington County will be closed early Sunday for the annual Marine Corps Marathon. Nearby streets will be crowded. Metrorail is the best way to get around whether you’re a participant, a spectator or just someone who wants to avoid traffic delays.

Metrorail opens at 5 a.m., two hours early. The closest station to the start line is Pentagon. The Arlington Cemetery station, a short walk from the finish, won’t open till 8:30 a.m. The runners begin at 7:55 a.m., and the marathon sponsors advise getting to the start area two hours early to get through security.

Halloween safety

Drivers, watch for children having some Halloween fun outdoors this weekend, when many neighborhoods will be holding afternoon parades.

On Wednesday, when trick-or-treaters are out, take extra precautions during the afternoon commute.

Slow down. Speeding makes it more difficult to stop unexpectedly. Be especially cautious between 4 and 9 p.m., the hours when children are most likely to be out. Enter and exit driveways slowly. Watch for children running across streets or darting out from between parked cars.

SoberRide program

The SoberRide program of the Washington Regional Alcohol Program will again offer free taxi rides home to adults who think they’ve had to much to drink on Halloween night and don’t want to risk driving.

The program will run from 10 p.m. Wednesday to 4 a.m. Thursday. A cab ride home will be free up to the equivalent of a $30 fare for passengers who call 800-200-8294 (TAXI).

Columbia Pike closings

From 9 p.m. Friday to 4:30 a.m. Monday, Nov. 5, Columbia Pike in Arlington is scheduled to close between South Quinn Street and South Orme Street while workers demolish part of the Washington Boulevard Bridge over Columbia Pike, the Virginia Department of Transportation said.

Drivers on Columbia Pike should follow the detour signs, as should drivers heading from Washington Boulevard to Columbia Pike. The closing is part of the bridge replacement project.

Hyattsville bus pad
L Street track

The District Department of Transportation is working along the north side of L Street NW to create a separated lane, called a cycle track, for eastbound bikers from New Hampshire Avenue to 12th Street NW. The job, which involves nighttime milling, repaving and lane painting, should continue for about two weeks. Concrete work will be done between 9:30 a.m. and 3 p.m.
