Pennsylvania Gov. Tom Corbett's transportation secretary says Interstate 81 and another road around the state capital will be closed for a few days after a tanker truck loaded with diesel fuel overturned and exploded.

Transportation Secretary Barry Schoch says the Thursday morning crash just outside Harrisburg damaged a section of Route 22-322 westbound and a ramp to it from I-81.

Schoch says he hopes I-81 can reopen early next week after a section of Route 22-322 above it is removed. He also hopes by Monday to convert one of the two unaffected Route 22-322 eastbound lanes into a westbound lane. He says the detour could last a couple months.

Turnpike tolls will be lifted at the Harrisburg East and Carlisle exits only to ease traffic congestion.

Police say the driver was treated for minor injuries.
