CORPUS CHRISTI - A tanker truck for liquid nitrogen caused quite a mess on Interstate 37 near Navigation Boulevard this morning when it crashed and blocked the road.
The driver of the Air Liquide truck admitted to police he dozed off just a little before hitting the guardrail near an overpass.
The front axle of the truck snapped, leaving the truck blocking all of the southbound lanes. Fortunately, the truck did not overturn.
Southbound traffic was diverted off the interstate for a couple of hours as crews ensured the cargo was safe and worked to clean up the damage.
The driver had just offloaded the tank of liquid nitrogen before the crash, so vapors seen escaping the tanker were just venting before the truck was towed.
The driver was not injured.
