A large sinkhole opened up in a Brooklyn street Tuesday afternoon, forcing crews to close the road to cars as they investigate.

Department of Environmental Protection crews were called to investigate the sinkhole at 56th Street between 6th and 7th avenues in Sunset Park.

It is not clear what caused the sinkhole to open up, but DEP crews are looking into whether water and sewer infrastructure played a role.

No injuries were reported.

Vehicles are not being allowed on the street. Pedestrians may walk through.

Chopper 4 footage from the scene showed cracks in the pavement on 56th Street. Cars are parked near the sinkhole, which is cordoned off with yellow tape.
