A gas leak prompted the evacuation of the Government Center, which was shut down for nearly five hours Monday morning.
Construction crews punctured a 6-inch underground gas line just after 8 a.m. while working in front of 10 Tremont St.
Gas leaked into the basements of surrounding buildings and the area around Court, Somerset and Sudbery streets was shut down as a precaution, CBS reported.
The streets reopened to traffic at about 12:30 p.m., WCVB reported.
Workers spent hours capping the leak and firefighters ventilated buildings.
