UPDATE: BFD reports second worker drowned.
A water main gave way shortly before 1:10 p.m. at Dartmouth and Tremont streets, with at least one worker trapped as the water rushed in. Around 2:20 p.m., the Boston Fire Department reported firefighters were draining the trench to recover his body.
Initial reports said two workers might have been trapped.
The Boston Police homicide unit was called in; routine when death is a possibility. Crime-scene specialists were also called in, as were inspectors from OSHA.

Traffic is, of course, a mess. BPS and BPD are working on getting school buses to a couple nearby schools to pick up kids when school lets out.
