Two lanes of the Capital Beltway’s outer loop are now open, with traffic getting by, but officials said delays remain after an early morning fatal crash closed the road for hours.

Still closed, officials said, are the two right lanes and a ramp lane near the Beltway and the northbound entrance to Interstate 95 near US 1 where the crash happened. It’s not known when they will reopen.

At least one person died in the crash that involved an SUV and a tractor-trailer. It happened around 4 a.m., and it was not immediately known if the cause of the crash was weather-related. But officials have had to deal with six other crashes along the Beltway in Virginia and Maryland, as light snow and rain fell in the region early in the morning and created slick spots on the roads.

Officials say all lanes of the Capital Beltway’s outer loop are closed after a tractor-trailer and SUV were involved in a fatal crash Friday morning near Interstate 95 and Route 1 in College Park, Md.

Maryland State Police said the highway will be closed for “an extended period of time” and likely through much of the morning rush hour.

Drivers are advised to avoid the area. Backups are building and reaching more than three miles.
