Wyoming’s Teton Pass reopens after devastating landslide

Wyoming transportation officials reopened Teton Pass on Friday following a catastrophic landslide that collapsed the roadway earlier this month.

According to the Wyoming Department of Transportation (WYDOT), Wyoming State Highway 22, Teton Pass, reopened at noon on June 28 with an interim detour around the Big Fill landslide at milepost 12.8.

Officials say that the current 60,000 pound gross vehicle weight restriction will remain in place when Teton Pass reopens. There will be no additional restrictions.

WYDOT says that the detour around the Big Fill landslide is 600 feet long, with a grade of 11.2 percent and a sharper curvature with a 20 m.p.h. speed limit.

“WYDOT’s professional geologists have evaluated the stability of the detour roadway. Geotechnical analysis confirms that the temporary detour meets or exceeds minimum requirements as outlined in guidance from the Federal Highway Administration,” the agency said.

Repairs are ongoing at the mudslide at mile marker 15.5.

The road collapsed on June 8, 2024, and crews from both Wyoming and Idaho have been working “around the clock” to repair the damage.

“We saw the viral video of the collapse, and it is a testament to the expertise and dedication of our Wyoming Department of Transportation that they were able to mobilize to construct this temporary road WYDOT is now working diligently on the next steps for the full rebuild, keeping motorist safety paramount,” Governor Mark Gordon said. “Our residents, commuting workforce and visitors – this road is open to you. I applaud everyone who has come together to solve this problem and help – that’s the Wyoming way.”
