This morning there was a major accident on I91 northbound at around 7:30 AM in which a truck going over the Williams Street overpass lost control of his vehicle, hit a minivan, and then crashed through the guard rail, coming down onto the slope just off the north side of Williams Street. From talking to the emergency workers at the scene, it appears that the truck caught fire on impact. According to WCAX, the driver of the truck was killed, while the driver and passenger of the minivan suffered minor injuries.
When I heard about the accident around 10:30 AM, I went over to see what had happened and took the following pictures.
Here's the minvan. Notice the guardrail missing behind.
