WATCHUNG - Utility crews are working to repair a large water main break in Watchung this morning.

American Water says the 12-inch main broke near Mountain Boulevard at Washington Rock Road. The utility says about 50 homes will be without water while repairs are made.

Police have shut down the roadway while crews work to fix the 50-year-old cast iron pipe.

A water station has been set up at the firehouse on Mountain Boulevard for those without water. American Water says there is no need to boil water at this time.
