Watch Massive Sinkhole Open Up at NYC Intersection

Firefighters responded at 7 a.m. Tuesday morning.

The estimated 20-by-20-foot hole formed around 7 a.m. at Fifth Avenue and 64th Street, ABC station WABC reported.

“It appears to be some sort of water leak that undermined the road, washed away the earth and that’s why the street gave way,” FDNY Deputy Chief Peter Leicht told WABC.

The surveillance footage shows the sinkhole undermining the roadway, which sinks underground.

Crews will work to excavate the area and determine the cause of the massive sinkhole, according to WABC.

There were no injuries to firefighters or pedestrians, the FDNY said.
