A water main break cut water service to about 150 homes in Mount Kisco Monday morning and also made a mess of traffic.

Water department officials say they got the call about the 10-inch water main pipe break at around 4:30 a.m. Workers cut into cement and blacktop after water caused the road to buckle, creating a sinkhole. Once determining the extent of the leak, workers found they had to dig up more road. Drivers on the heavily-trafficked Route 133 suffered delays.

Officials say the water main break may have been caused by the ground shifting or even the drastic changes in temperatures.

?This I think is the second time in the past few months we've lost water here, but it happens,? Mount Kisco resident Darius Powell says. ?It's just unfortunate it happened on a Monday morning.?

There is no word on how long the repairs will take. Crews say they'll be working on it most of the day, which means traffic tie-ups will continue.
