Update, 4:15 p.m.: As crews began to try to get the cab back behind the guard rail, the MBTA shut Orange Line service, just in case, because the tracks run right under the crash site.
A crash involving a big truck and a small truck on I-93 north in Charlestown around 2:10 p.m. sent the larger vehicle dangling over the guardrail and the driver of the smaller truck to the hospital.
The larger truck, a Michelob tractor-trailer, ended up with its cab dangling off I-93 over the Leverett Connector, in the same general area as the voodoo Globe-truck incident a few days ago.
State Police shut the road in both directions as firefighters tried to deal with a detached fuel tank that was leaking across the road. Debris showered the connector ramp below.
