A hazardous materials crew is on the scene of a tractor-trailer crash in Lackawanna County.
The truck carrying phosphoric acid overturned Wednesday morning at the off-ramp of Interstate 81 north at the Scott/Route 524 exit (199).
The driver and his passenger were not hurt.
Route 524 is also closed in both directions at I-81 to the intersection of Routes 347/250 in Scott Township.
A truck has to come from New Jersey to empty the acid from the overturned truck before the truck can be moved.
Officials said the hazardous materials crew has a small leak in the truck under control.
PennDOT expects the ramp and road to reopen around 1 p.m.
