The bridge collapsed at Kenilworth Avenue and Polk Street NE, the agency said in a tweet. Four people were transported to the hospital, but there were no reports of anyone trapped in the debris, the agency said.
Images posted by DC Fire and EMS show the bridge’s mangled concrete and metal sprawled across all six lanes of highway and sitting on top of several vehicles.
A hazmat unit was on scene mitigating a diesel fuel leak from a truck that is partially beneath the bridge, and at least one other vehicle was struck by debris, DC Fire and EMS said.
Washington Metropolitan Police Department are in the early stages of investigating the cause of the collapse, said department spokesperson Alaina Gertz.
