A pedestrian bridge collapsed Wednesday onto DC-295 in Northeast Washington, trapping a truck that started leaking diesel fuel and leaving at least six people injured, WBAL-TV's sister station, WRC, reported.

The bridge collapsed near Kenilworth Avenue. Firefighters checked for cars underneath the collapsed bridge and reported no one was trapped.

Four people were taken to a hospital and two others were assessed, according to D.C. Fire and EMS.

WRC reported at least two vehicles appeared to be under the fallen bridge below a large sign for the Benning Road exit.

It was not immediately known what may have caused the collapse or whether anyone was walking on the bridge at the time.
