PHILADELPHIA—The driver of a tanker truck hauling gasoline lost control on a curved off-ramp on Interstate 95, causing the truck to flip and catch fire, leading to the collapse of the northbound lanes in early June, federal safety officials said Thursday in a preliminary report.
The National Transportation Safety Board’s brief report outlined what happened on June 11, when an elevated section of Interstate-95 collapsed after the tanker truck caught fire underneath it. It largely confirmed what state officials said earlier.
