Teton Pass Highway Safety

Wyoming Highway 22 crosses Teton Pass at 8,431 feet — the steepest roadway in Wyoming, serving roughly 8,000 commuters, trucks, and travelers every day. This page is where we track the issue, share what's being proposed, and give you a way to weigh in.

The issue

The Teton Pass / Highway 22 has been the site of many vehicle accidents. Since its opening in 1969, there have been 34 fatalities. The five-year period from 2016 to 2020 saw eight fatal crashes, 60 injury crashes, 78 intersection-related crashes, and 244 property-damage-only crashes — an average of 62 crashes each year. According to WYDOT, accidents in this area have increased by 20% over the last five years alone. These incidents form a pattern that supports the claim that Teton Pass Highway is unusually dangerous and in need of changes to improve its safety.

Teton Pass Highway Safety

Two hundred people showed up for the Teton Pass Highway Safety Meeting at the Old Wilson Schoolhouse on August 3rd — residents and business owners from Idaho and Wyoming, Wyoming state senators and representatives, the Mayor of Driggs, county commissioners from both Teton counties, staff from WYDOT and ITD, the Wyoming Highway Patrol, the Teton County Sheriff's Office, and trucking company owners. A standing-room-only crowd came ready to change how the Teton Pass highway looks and how it operates.

Where we are now:

We are a coalition with a common goal, working across state and county lines for the good of the greater Teton community. Six weeks ago, none of this was true.
