Chunks of concrete debris from a bridge on the Beltway Outer Loop fell below onto the Interstate 270 spur in Bethesda, Maryland, on Sunday, prompting officials to close part of the roadway, WTOP Traffic reports.

An overnight crash on the Outer Loop on the big curve damaged the bridge, causing portions of a concrete wall to break off and land below on the right shoulder of the I-270 spur southbound.

Maryland State Highway arrived on the scene in Montgomery County around 10 a.m. Traffic is partially blocked on I-270 near where the interstate joins with the Beltway as officials investigate.

By Sunday evening, a few pieces of concrete, each around the size of half of a brick, were swept off the roadway into a nearby wooded area.

A spokesman with Maryland State Highway Administration said all lanes were expected to reopen in time for Monday morning’s commute.

The road was shut down hours after the destructive crash while a temporary repair was underway; the Outer Loop bridge in that area remained open. Officials said a repair was completed by 8 p.m. Saturday and all lanes were reopened.

Maryland’s highway administration is looking into the timing of the accident. The state highway administration said there were no reports of debris from the crash affecting traffic on I-270.

WTOP’s Steve Dresner, Ivy Lyons and Jessica Kronzer contributed to this report.

Zooming past a stopped DC school bus comes with $500 fine this school year

Ahead of Monday’s first day of classes, D.C.’s Department of Transportation is reminding drivers that zipping around stopped school buses will come with a hefty fine this school year. The program, which launched in the final weeks of the last school year, added cameras to 25 school bus stop arms. When the bus is stopped — its stop arm is extended and the lights are flashing — cars can’t pass the bus on either side of the road, unless there’s a median in between the two lanes.
