A manhole exploded shortly before 6 p.m. at Cambridge and Bowdoin streets, sending two Eversource workers to Mass. General, one with life-threatening injuries, and creating massive traffic issues in the area.
From across the street, Sonya Dunne reports:
Sounded like the Hill was exploding. Really bad. Could hear the guy. Can't stop shaking and crying. These first responders are amazing people. Ran right in. God Bless them. Christ.
Boston Fire and Eversource crews are figuring out how to deal with the explosion in an underground transformer "vault." OSHA will launch an investigation tomorrow.
