CAMBRIDGE, Mass. — Repairs are still ongoing after multiple manhole explosions rocked Cambridge’s Harvard Square.
Traffic is down to one lane on Brattle Street and the sidewalk remains closed to pedestrians as crews continue to assess connected manholes in the area.
Firefighters responded to a report of a fire in the area of 27 Brattle Street around 9 a.m. on Wednesday and found a smoking and flaming manhole, according to the Cambridge Fire Department.
Firefighters were able to shut off power to the first two manholes, but it took hours for them to find the power source to a third manhole that was burning.
Video captured by a Boston 25 photographer showed a massive plume of flames erupting from one of the manholes as emergency officials looked on.
“I see smoke, I walk over, and the manhole is gone. There’s fire coming out of the manhole,” said Toby Coban, who witnessed a blast. “Shortly after it blew up, they opened it and it blew up again. A big fireball came out of the manhole, a big smoke ring.”
This caused carbon monoxide to leak into area buildings and forced businesses to close for the day. Several places, like the Harvard University Bookstore, had to be ventilated.
One firefighter did have to be taken to the hospital but is expected to be okay.
The cause of the blasts is unknown and it’s unclear when everything will be fixed and reopened.
This is a developing story. Check back for updates as more information becomes available.
