N, Q, R, and W subway service is back to normal after a water main break in Brooklyn Heights on Thursday afternoon.

The MTA said the call came in for a water main break on Montague and Clinton St. around 3:30 p.m.

Water flooded the busy area before it poured into the Court St. subway station.

Several businesses were forced to shut down after they were left without running water and electricity.

The DEP says it shut off a 12-inch water main, which stopped the leak.

Crews were at the station to make sure the water completely drained.

R trains ran along the Q line from Canal St. to DeKalb Ave earlier in the day.

N, Q, R, and W trains were delayed Thursday evening as a result of the situation.

Subway service has resumed, and most businesses expect to reopen later Friday.
