From the Department of Public Safety:
A tractor trailer carrying paper has rolled over on Route 27 in Coburn Gore, south of border crossing into Quebec.
The truck collided with a bridge as State Police, MaineDOT Bridge Inspectors & DEP are currently on scene.
Commercial Traffic was stopped and held at the port of entry for about 1 hour until the DOT Bridge could clear access over the bridge. That has now just been cleared and traffic is rolling again.
Driver sustained some injuries and was being transported to be evaluated. Paper was all over roadway and into a stream. Cleanup operations are currently underway.
