A 127-year-old water main under New York’s Times Square gave way early Tuesday, flooding midtown streets and the city’s busiest subway station, writes ABC NEWS.

The 20-inch (half-meter) pipe gave way under 40th Street and Seventh Avenue at 3 a.m., and quickly delivered a wet reminder of the perils of aging infrastructure beneath the city’s crowded streets.

The rushing water was only a few inches deep on the street, but videos posted on social media showed the flood cascading into the Times Square subway station down stairwells and through ventilation grates. The water turned the trenches that carry the subway tracks into mini rivers and soaked train platforms.

It took DEP crews about an hour to find the source of the leak and shut the water off, said Rohit Aggarwala, commissioner of New York City’s Department of Environmental Protection.

The excavation left a big hole and a muddy mess in one city intersection where workers dug with heavy equipment to get to the broken section of pipe.
