HARRISBURG — A section of Interstate 81 near Harrisburg was expected to remain closed in both directions for the next several days after a tanker truck fully loaded with diesel fuel overturned Thursday morning and exploded into flames, sending black smoke billowing into the sky.
Officials said the crash occurred on an on-ramp to Route 22-322, where the ramp curls back over the interstate and runs under another section of Route 22-322. They said the intense heat buckled steel beams on the top section and damaged it so badly there were fears it could collapse and fall onto I-81.
“There really could not have been a worse spot for this to have occurred,” state Transportation Secretary Barry Schoch told reporters.
State police said the driver, Thomas Uecker, 52, of Dover, was treated at a hospital for minor injuries. The truck was registered to Tameric Enterprises LLC in Carlisle.
The truck, carrying 7,500 gallons of diesel fuel, was headed northbound from Carlisle shortly after 6 a.m. when it flipped over on the ramp, just north of where I-81 crosses the Susquehanna River.
Officials announced plans to tear down the heat-damaged top level, and were working to contain and clean up about 2,000 gallons of fuel that spilled into nearby Paxton Creek and the lake at Wildwood Park and Olewine Nature Center, a county park that borders the interstate.
Schoch said the heat from the fire was so intense that it forced water out of concrete as steam, generating explosions. A specialist was helping state officials assess damage to the bridges’ steel structures.
State police said they were still investigating the cause of the crash, which caused damage estimated at more than $10 million. Uecker did not appear to have a listed home phone number, and a message left for Tameric Enterprises on Thursday was not immediately returned.
“We have no clear timetable ... as to when the repairs will be completed,” Gov. Tom Corbett said.
The Pennsylvania Turnpike is waiving tolls for motorists who drive between the Carlisle and Harrisburg East exits as an alternative to I-81.
Motorists must take a ticket at one exit and present it at the other to get the free tolls. E-ZPass users can enter and exit the turnpike normally and not be charged for trips between those two exits, which are about 21 miles apart.
