Metro has resumed running its buses but with limited service after heavy snow left roads in icy conditions.
Early Monday, Metrobus said it is running on a “severe snow plan due to road conditions.” Officials said Metro buses will be running on major roadways only and that riders should expect delays.
Metro’s rail system is running on a normal schedule.
MARC commuter trains in Maryland are on a limited "R" schedule because of the weather. And VRE commuter rail in Virginia shut down its service for Monday.
On Sunday night, Metro suspended its service because of the icy road conditions.
Between eight and 12 inches of snow fell throughout the D.C. region over the weekend. Many local courts, government offices and schools are closed for the day.
Early Monday, there were no reports of major delays or crashes on the big commuter routes. Transportation officials warned drivers to stay off the roads so that crews could work to clear area side streets.
In Northern Virginia, officials at the state’s transportation department said early Monday morning that the primary and interstate roads were “good.” Crews were now focusing on roads in subdivisions.
They warned, however, that it will take time to clear the 16,000 streets in subdivisions in the area. The agency said that it typically takes up to 72 hours to clear roadways if the region gets more than six inches of snow.
Drivers are advised to stay off the roads so area crews can clear them. Pedestrians and drivers who do have to go out are advised to allow extra time and be patient, and watch out for icy spots on sidewalks and roads.
There were reports of several crashes over the weekend on icy, snowy roads.
