Road Work near Moran in Grand Teton: Expect Delays

If your trip out West takes you through Grand Teton this fall, keep an eye on road conditions. The National Park Service is starting construction on US Highway 26/89/191 in the Moran area starting in October 2026. This isn't a minor road: it's one of the main routes into the park, and it runs north toward Yellowstone.

There's a clear reason for the work. Significant erosion is undermining the roadway at the confluence of the Snake River and Buffalo Fork, and that's the spot crews are coming to shore up. This is no small thing: when a river eats away at a road's embankment, repairs become unavoidable sooner or later.

For you, that means planning ahead. Construction on a road this busy almost always brings delays, alternating one-way traffic, or wait times, especially during the hours when everyone's driving out to the overlooks. Build some slack into your travel times, especially if you're aiming for sunrise or sunset over the Teton Range.

We don't know the detailed schedule or exactly how long the work will last yet. Check road conditions right before you head out, since they change from week to week. The rest of the park is still open as usual: the work affects one stretch of road, not access to the trails or lakes.

To place Moran in context and plan your stops with confidence, lean on the Grand Teton park guide. And if you're continuing on to its neighbor up north, our road trip itinerary through this park follows this very connection, so you can set your timing around the construction.
