Crash Blocks All Beltway Outer Loop Lanes in Prince George's County

All outer loop lanes of the Capital Beltway shut down in Prince George's County early Sunday morning after a multi-vehicle crash near the MD 201 and US 1 corridor, snarling traffic during one of the busiest stretches of the regional commute.

Officers responded to the report of a crash at 5:11 a.m. When they arrived, they found multiple cars involved and immediately blocked multiple lanes, triggering backups that stretched as far as four miles along the Beltway. A separate report placed a multi-vehicle collision on the inner loop at MD 414, also blocking the right and left travel lanes, though whether that crash and the outer loop incident were the same event or two separate collisions had not been confirmed as of early Sunday morning.

At least one person was injured in the crash, though the severity of that injury was not known. The cause remains under investigation, and police had not released additional details.

By 7 a.m., all travel lanes were open to traffic and residual delays were dissipating, ending roughly two hours of major disruption on one of Maryland's most heavily traveled highway segments.

The Capital Beltway corridor through Prince George's County has long been subject to both crash-driven and planned closures. The Maryland State Highway Administration has previously conducted overnight concrete deck work on the Beltway bridge over Suitland Parkway, requiring closures of three left lanes on the I-95/I-495 outer loop between MD 5 (Branch Avenue, exit 7) and the Suitland Parkway bridge. During those work zone periods, the agency urged drivers to stay alert, slow down, and avoid following too closely, noting that each driver must "actively modify his or her driving style to help prevent crashes."

Drivers navigating the Beltway can reach Maryland's free 511 traveler information service by calling 511 or 1-855-GOMD511, or by visiting md511.org, where personalized route alerts are available through the MY511 signup. Maryland law prohibits hand-held mobile phone use and texting while driving, including when accessing the 511 system.

The investigation into Sunday's crash is ongoing. No charges had been announced and no official incident report had been released by county or state police as of the time of initial reports.
