Grand Teton National Park Construction Updates
Nature has been reshaping this landscape for millenia. We’re just lending a hand.
The Grand Teton National Park construction schedule below shares when popular roads will be closed or expect delays. Death Canyon trailhead will be closed for the entire summer 2026 season; Moose-Wilson Road between Moose and Laurance S. Rockefeller Preserve will see construction and delays; and work on the Taggart Lake Trail will require a longer, steeper re-route.
We’re on the wild’s timeline here, and dates are subject to change.
