Boston Water and Sewer Commission crews worked Monday morning to repair a water main break in downtown Boston that shut down a part of Interstate 93 near the O'Neill Tunnel.

Crews started working late Sunday night to contain the break, which flooded Summer and High streets near South Station. The water impacted several services and closed Exit 20A on I-93 southbound to traffic, according to the BWSC and the Massachusetts Department of Transportation.

"A private contractor working on a pipe apparently disrupted the existing 24-inch service pipe that was adjacent to it and it broke," BWSC spokesperson Tom Bagley said.

Police have since reopened the area on Summer Street between Purchase and Lincoln Streets as well as Exit 20A.

The water was temporarily shut off while crews pumped and made repairs, Boston Water said. New pipe was laid and service was restored.

Boston police were on scene since shortly after 9:30 p.m. Sunday to assist with traffic in the area of Summer and Purchase streets.

"There were some flooding issues on the Southeast Expressway last night. We had to close the Expressway for about 30 minutes to an hour. Once that water drained, we opened up again," Bagley said.
