A pickup truck with a flatbed trailer that was carrying 32 logs sailed through all eight catchnets on the Teton Pass truck arrestor Tuesday evening.
The arrestor will remain closed until the Wyoming Department of Transportation can evaluate it, a release from WYDOT said.
“The vehicle arrestor did not perform as expected,” WYDOT District Engineer Keith Compton said. “We will be analyzing the system and how it functioned and take necessary steps to correct any noted problems.”
The driver refused treatment and did not have serious injuries, Jackson Hole Fire/EMS Fire Marshal and incident commander Kathy Clay said.
The truck jackknifed and came to rest after it passed through the arrestor, with most of its logs ending up 200 feet downslope.
“The truck is obviously demolished,” Clay said.
Wyoming Highway Patrol is investigating the incident, Wyoming Department of Transportation spokeswoman Stephanie Harsha said.
Opened in March 2017 near milepost 7 on the south side of Highway 22, the truck arrestor was installed to replace a runaway truck ramp, which trucks had to cross uphill traffic to use. This is the fifth time the arrestor has been used, WYDOT officials said.
