- Federal officials say the driver of a tractor-trailer that overturned and sparked a blaze underneath a major Philadelphia interstate that resulted in a collapse had failed to slow down on the exit ramp.
- The National Transportation Safety Board issued its final report in the June 2023 crash at an Interstate 95 exit ramp and “found probable cause” that the driver, who was killed, exited the highway above the posted speed limit and possible fatigue played a role.

There were no other deaths or injuries.
it was a driver of a tanker
Still true. Emergency response should be able to get there on time before tons of concrete gets weak.
There’s a ridiculous amount of energy being released all at once with a burning tanker. Bridges are of made steel and concrete, not magic!
This is precisely the reason hazardous materials are banned from being transported in tunnels. A cars worth of energy being torched? Sure. A tanker carrying several thousand cars worth of energy is a different beast altogether.
Several years ago I was unlucky enough to be stuck on I40 going thru NC when this same thing happened and wouldn’t had believed it if I hadn’t seen it - or rather seen it a few minutes after it happened.
A tanker truck of gas hit an underpass and exploded (under the bridge). It got so hot - so quickly - it melted the bridge/beams/etc.
Traffic was backed up for hours before it was rerouted (our car included) and I think it took them a year or more to get that particular intersection rebuilt.
