A gas leak in Southbury on Wednesday led to several road closures. The leak, caused by a third-party contractor hitting a gas main, prompted the closure of Exit 14, Main Street South at the intersection of Route 172, and the area near 775 Main Street South. Eversource crews quickly brought the situation under control and made temporary repairs, but the damage will take time to fully fix. No customers were affected, but traffic in the area will remain impacted as repairs continue.
