WYDOT Overhauls Teton Pass Signs Ahead of Winter

JACKSON, WY — Starting Monday, Sept. 21, WYDOT crews will spend three days putting up new signage on Teton Pass, with lane closures and flaggers on Highway 22 from 9 a.m. to 3:30 p.m. each day.

The headline change isn’t just new paint. It’s who the signs are actually talking to.

What WYDOT Says It’s Doing

According to WYDOT, the work covers three things: new “Must Stop Brake Check” signs at the summit, “No Parking” signs at the gravel escape ramp and vehicle arrestor system, and a wholesale rewording of the roughly 50 grade-warning signs between the state line and Wilson.

District 3 Area Traffic Supervisor Tara Finley says the upgrades have been sitting in the queue for weeks. “The planned upgrades for these signs have been in the works for several weeks. We have been waiting on fabrication,” Finley said.

In plain English: the state has known what it wanted to do for a while. The signs themselves were the bottleneck.

What the Proposal Actually Includes

The most notable change is semantic, not physical. Signs currently warning “Truckers” about sharp curves, steep grades, and staying in low gear will now say “All Vehicles.”

If you’ve driven the Pass in a Subaru and watched a sedan ride its brakes down from the summit like it’s still 1998, you already know why that word mattered.

District 3 Traffic Engineer Darin Kaufman put a number on the scope: “We have about 50 signs from the state line to Wilson informing drivers of steep grades and to use low gear. WYDOT is currently working on reviewing the rest of the signs and their placement.”

WYDOT is also designing diagrammatic “you are here” map signs that illustrate the grades, restrictions, and the Swan Valley alternate route — the same style already used on US 16 and US 14A. Those are planned for the scale house, the state line, and the summit turnout, installed as each sign is fabricated.

Why This Matters Here

Teton Pass is not a scenic drive with a warning label. It’s a commuter road for a huge share of the valley’s workforce, and it has a well-documented habit of eating brakes, cars, and patience.

We’ve written before about the plan to fix Jackson’s worst white-knuckle left turn with a tunnel under WY-22 down in town. This is the same instinct applied uphill: the infrastructure conversation in Teton County keeps coming back to the fact that there is exactly one good way over the hill, and it punishes people who treat it casually.

Relabeling signs from “Truckers” to “All Vehicles” sounds small. It isn’t. Every winter, Jackson Hole’s weather turns the Pass into a different road entirely, and the drivers who get in trouble up there are rarely the CDL holders. They’re the rental car, the out-of-state plate, the guy who assumed “low gear” was somebody else’s problem.

The Questions Worth Asking

WYDOT says it’s “actively reviewing safety improvements and future infrastructure enhancements” as part of the State Transportation Improvement Plan process. That’s the kind of sentence that means something is happening, eventually, on a timeline nobody in this press release will commit to.

So: is new signage a fix, or a placeholder while the bigger infrastructure questions get worked out in committee?

And will drivers actually change behavior because a sign now says “All Vehicles” instead of “Truckers”? Signage assumes people read signs. Teton Pass has spent decades testing that assumption.

The Bottom Line

This is a real, if modest, safety upgrade — better warnings, clearer maps, a parking rule at the arrestor bed that should have existed already. None of it replaces the harder conversation about long-term capacity and resilience on the Pass, which is still grinding through the planning process.

In the meantime, WYDOT’s actual advice hasn’t changed: wear your seatbelt, slow down, use low gear on the way down, and put the phone away. Sign up for 511 Notify alerts if you drive the Pass regularly — wyoroad.info/511 — because “unpredictable weather” up there is not a disclaimer. It’s a forecast.
