Northbound at Roosevelt Circle, Ben Jackson tweets. Based on the comments below, sounds like everybody got out OK.
Just saw some video on the news. Looks like the fire was contained to the middle section of the bus. Also looks like the bus was safely pulled over to the shoulder, so I think it is possible that there was no accident involved and hopefully any passengers now have nothing more than a good story about their New Year's Eve 2010.
while they attended to the fire, but WBZ is reporting that all lanes are now reopened.
Your map places the fire at the Salem Street Rotary, not Roosevelt circle, which is north of this rotary at Rt. 28 in Medford.
