Eastbound Broad Street was closed for several hours in Stamford Thursday due to a water main break.

The water main break on Broad Street and Grove Street caused heavy delays in the area.

Aquarion Water Company said a 12-inch valve had to be replaced on a 12-inch water main break near 200 Board Street.

As a result, more than 100 apartments at the Canterbury Green building were out of running water for most of the day.

Officials say more water main breaks happen during the winter because of frigid temperatures and shifts in the soil.

Police say streets should reopen on Friday.
