Three Main Street buildings in Cambridge are without water after a pipe burst this afternoon, according to a city spokesman.

An old cast iron pipe burst, causing minor flooding in front the American Red Cross building at 139 Main St. at about 2:30 p.m., according to Lee Gianetti, director of communications for the City of Cambridge. The leak was caused by cold temperatures, he said.

“When the weather gets cold it, can sometimes cause problems with these pipes,” said Gianetti.

The Red Cross building, along with two brick office buildings near the site, will be without water until about 8:30 p.m., said Gianetti.

Traffic was not affected by the burst, because the lane was already closed due to construction at the nearby Longfellow Bridge, said Gianetti.
