A devastating landslide has closed a mountain road between Wyoming and Idaho that could threaten access to national parks, among other things.

The incident happened Saturday.

The road linking the two states is expected to be closed indefinitely.

Wyoming Gov. Mark Gordon wrote on Facebook that the road connects Victor, Idaho and Jackson, Wyoming, and is part of the Teton Pass.

Wyoming Department of Transportation (WYDOT) officials said the first cracks started to appear on Thursday and were as deep as eight inches in some places, making driving conditions unsafe. Although the initial cracks were able to be patched, a later landslide collapsed the road.

“WYDOT crews, along with contract crews from Evans Construction, were working in the area to construct a detour around the damage, but the landslide continued to move, taking out the whole road,” WYDOT wrote. “No crews were hurt in the process, and no equipment was damaged.”

Gordon called it "catastrophic."

“I am grateful for the efforts of WYDOT staff to protect public safety during this developing situation, and am thankful no one was injured during this incident,” the governor said.

Repair work is ongoing but there is no timetable.

“WYDOT engineers, surveyors and geologists mobilized quickly to try to maintain highway viability as long as possible, but catastrophic failure could not be avoided. WYDOT remains on site decisively engaged on fixing the road and restoring connectivity to the Teton Valley,” WYDOT Director Darin Westby said in a statement.

The Teton Pass includes Grand Teton National Park and “serves as a critical commuter route and facilitates the transport of goods and services that are lifelines to the growing regional economies in Wyoming and Idaho,” according to the U.S. Department of Transportation.

It is not the first time something like this has happened.
