Grand Teton National Park announces major infrastructure enhancements beginning in 2026

Date: May 13, 2026

MOOSE, Wyo.— Grand Teton National Park will open its 2026 summer season with a series of significant infrastructure improvement projects that may impact road and trail access in some areas through mid-November. Please check current conditions and plan alternate routes before visiting the park.

“This work represents an important investment in the future of Grand Teton National Park as we approach the park’s 2029 centennial,” said Superintendent Chip Jenkins. “The improvements underway over the next several years will help ensure visitors can safely access and enjoy this landscape while we continue to protect the resources that make it so special.”

CONSTRUCTION PROJECTS
Moose-Wilson Road, Death Canyon Road and Death Canyon Trailhead
Phase 2 of the multi-year Moose-Wilson Road rehabilitation will improve Death Canyon Road and Trailhead and construct a road realignment near Moose.

Key dates and access information:

• Moose-Wilson Road between the Granite Canyon Entrance Station and the Laurance S. Rockefeller Preserve is open. The northern segment between the preserve and Moose will open June 20. From June 20 to September 7 (Labor Day), visitors should expect intermittent delays of up to 45 minutes or longer as materials and equipment move through the corridor.
• Death Canyon Road and Trailhead (accessed via Moose-Wilson Road) will be fully closed through mid-November, with a delayed reopening anticipated in 2027.
• Initial construction for a roundabout near the Moose Entrance Station will begin this summer, affecting Teton Park Road near Moose. Visitors should expect delays while crews construct a temporary bypass ahead of construction in 2027. The multi-use pathway will remain open, and bicycling north from Moose is a good alternative for reaching destinations like Jenny Lake.

Taggart Lake Trail
The northern segment of Taggart Lake Trail, between the first junction and Bradley Lake Trail, will be closed through November 15, 2026 for trail rehabilitation. Work includes repairs, regrading, and accessibility improvements to enhance the visitor experience, particularly for families and visitors with mobility needs. The Taggart Lake Trailhead and parking area will remain open. Cottonwood Creek Picnic Area will remain open through late summer. Taggart and Bradley lakes will still be accessible via alternate marked trails.

This renewal effort is supported by Grand Teton National Park Foundation in partnership with Grand Teton National Park.

Mormon Row Historic District
Mormon Row will remain open throughout the season. Construction is scheduled from mid-June through mid-November. Visitors should expect construction equipment, noise, and localized disruptions.
The project expands pedestrian and cyclist access and includes accessibility improvements. This is the final phase of a multiyear project funded by Grand Teton National Park Foundation in partnership with Grand Teton National Park.

North Park Road (Highway 89/191/287)
Construction between Leeks Marina and Lizard Creek Campground will result in nighttime delays of up to one hour between 9 p.m. and 6 a.m. Daytime travelers should expect delays of up to 15 minutes due to one-lane alternating traffic. 

TRIP PLANNING AND INFORMATION
2025 was the park’s second-busiest year on record, and visitation is expected to remain high in 2026.

Visitors are encouraged to:

• Purchase park passes in advance at recreation.gov or at select community locations to reduce entrance station wait times.
• Check current road and trail conditions before traveling.
• Allow extra travel time and plan alternate routes, especially during peak summer periods and holidays.
• Consider exploring less-visited parts of the park such as the Colter Bay area.

Up-to-date construction schedules and conditions will be posted at nps.gov/grte and on the park’s official social media channels.
