The water main break, which happened around 1:45 p.m., also flooded the roadway in the area, snarling vehicular traffic, police said.

A water main break on the Upper West Side disrupted subway service on the busy B and C lines Wednesday afternoon. A and D service was also impacted.

Multiple subway lines suspended service in Manhattan just ahead of the evening rush — and as the holiday travel rush was already underway — due to a water main break, according to officials.
