Overview
- The break around 6:30 a.m. on Grove Street sent water under the pavement that eroded the roadbed and caused sections to buckle and cave in.
 - Police closed Grove Street between Knoll and Oak Hill, with parts of Oak Hill Road impassable and detours via Nabnasset Street and Brookside Road.
 - National Grid cut gas and electricity in the area for damage assessment and safe cleanup, as several homes reported flooded basements.
 - Residents near the collapse lost water service and, in some cases, vehicle access, while crews removed damaged pavement and evaluated the site.
 - Town officials said they aim to restore water and gas by Monday evening and plan repaving in the coming days, but no reopening time has been set; discolored tap water is not considered a health risk.
