BOSTON HEIGHTS — A disabled tractor trailer truck caused the shutdown of the southbound entrance ramp to Route 8 from Boston Mills Road Friday morning, Police Chief Ray Heatwall said.

Heatwall said that at about 9 a.m. the truck’s drive shaft broke, punctured at least one fuel line and 75 to 100 gallons of diesel fuel spilled out onto the road. He said cleanup should be completed by 1 p.m. and the ramp reopened.
