A water main break temporarily suspended subway travel on large portions of four Manhattan lines early Wednesday morning and its effects are still being felt during the morning rush hour commute.

At 12:45 a.m., a 12-inch water main burst at 105 Street and Central Park West in Manhattan Valley.

Water flooded the streets and cascaded down to underground subway stations' tracks.

The Metropolian Transportation Authority, as a result, temporarily suspended service in both directions on the A and C trains between 59th and 105th Streets, and B and D trains between 34th and 145th Streets.

At 7 a.m., the MTA announced service on the lines have resumed with residual delays.

Straphangers can also expect delays and detours on the M10 bus route, which runs along Central Park West.

According to the Fire Department of New York, no homes or businesses were evacuated.

The Department of Environmental Protection said about 200 families in three buildings will be without water until about 12 p.m. Wednesday.

At this hour, crews have stopped the water flow and have begun repairs.

DEP spokesman Michael Saucier told PIX News about 10 feet of pipe will have to be replaced for normal water service to resume.

The cause of the water main break is under investigation, but the DEP suspects it was due to the cold weather and old age.

The now-broken pipe was installed in 1889.
