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.

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 multiple lines Wednesday afternoon.The break happened at 103rd Street and Central Park West at 1:50 p.m. and involved a 12-inch main.
