Teton Pass Now Open!
WY22: Teton Pass is now open with an interim detour around the Big Fill landslide at milepost 12.8. Crews are currently striping and placing barrier. WYDOT estimates the road to open around midday Friday, June 28. Drivers are encouraged to sign up for 511 Notify alerts at https://www.wyoroad.info/511/
The current 60,000 lbs gross vehicle weight restriction will remain in place as the road opens. There will be no additional restrictions. Trailer traffic will be allowed, but WYDOT encourages drivers to be cautious and aware of the reduced speed and obey all traffic signs.

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 calculated factor of safety for stability of the detour exceeds 1.2, with 1.1 being the minimum acceptable to WYDOT’s professional licensed engineers.
Alternate Route to the Detour:
The new Teton Pass detour is the most direct route between Jackson, WY and Teton County, ID where we are located. There is also a longer, alternative route that adds about 45 minutes to travel time, making it about 1.5 hours, depending on traffic and road conditions. It is a very scenic along the Snake River through the Snake River Canyon, along the Palisades Reservoir and up and over Pine Creek Pass. It’s truly one of the more beautiful drives in the Teton region.
