A tractor-trailer roll-over on Interstate 195 Westbound is causing traffic backups. The mishap happened just before 9am.

The tractor trailer was reportedly carrying a load of construction material that spilled over the roadway. According to State Police in Dartmouth, the driver suffered minor injuries, but no other vehicle was involved. There is also a fuel spill on the roadway.

Mass. Highway has now responded to the scene. State Police say only the high speed lane is open, and its likely the cleanup will take awhile.

Traffic is reportedly backed up past Route 18.
