BILLERICA -- Billerica police are asking drivers to seek alternate routes around the area of Boston and Webb Brook roads while crews work overnight to repair a water-main break near the intersection.

Police reported via their official account on Twitter that the water-main break was "causing a significant mess" that would necessitate closing Webb Brook Road between Boston Road and the Elks Club.

Police also said closures on Boston Road (Route 3A) would be needed during the overnight hours.

It was not immediately clear if the water-main break affected service for residents.
