CHESTNUT HILL, Mass. (WHDH) — A construction crew accidentally severed a gas main Monday afternoon.

A backhoe broke the 4-inch main out on Commonwealth Avenue right next to an assisted living facility. The building was immediately evacuated, and no injuries were reported.

Gas officials are still monitoring the area. The gas break also affected the MBTA’s green line but service has returned to normal by the early evening.
