The four-lane highway overpass south of downtown that burned for hours after a tanker truck crashed below it must be torn down and rebuilt, state transportation officials said late Monday.
“A lot of factors go into play here, but it is a priority, and we are going to get it open as soon as possible,” said Kelli Petras, a Dallas TxDOT spokeswoman.
A tanker truck hauling thousands of gallons of fuel slammed into a retaining wall on a bend of Highway 175 known as Dead Man’s Corner about 5 p.m. Sunday. A spectacular fire burned near the corner under the four-lane overpass for about two hours.
On Monday, TxDOT engineers evaluated the bridge’s structure, which was riddled with loose concrete.
The southbound lanes of Highway 175 – including Dead Man’s Corner – will remain closed at least through the overpass demolition process, Ms. Petras said. Northbound lanes are expected to be open.
One northbound lane of State Highway 310 will remain open until the demolition begins, possibly within days, Ms. Petras said.
The closures caused 20-minute backups Monday.
Robert Lee Pride, 27, the driver, told police that his front right tire blew, causing him to lose control, said Kim Leach, a Dallas County sheriff’s office spokeswoman. The accident report also cited speed as another possible cause of the accident.
Investigators have not been able to determine how fast Mr. Pride, a Dallas resident, was going as he tried to navigate the near-90-degree turn, Ms. Leach said.
The tanker was registered to United Petroleum in Oklahoma.
Ms. Leach said she didn’t know whether Mr. Pride had been cited in the accident. He could not be reached for comment Monday.
Mr. Pride suffered minor injuries. No one else was hurt.
TxDOT crash statistics show there have been 43 accidents at the interchange over the last five years, including three fatal accidents.
Ms. Petras said the curve has some design flaws, but it can be navigated safely.
“Just because we don’t design them like that anymore doesn’t mean they are dangerous,” she said. “It just means you have to follow the signs.”
