CLOSURES & CONSTRUCTION UPDATES:
Moose-Wilson Road and Death Canyon
Phase two of the park’s multi-year project to rehabilitate the Moose-Wilson Road is in full swing this season. Here is what visitors need to know:
Moose-Wilson Road opens for the season on May 1, but will be closed between the Laurance S. Rockefeller Preserve and Moose from May 1 through June 20. From June 20 through September 7, travelers can expect intermittent delays of up to forty-five minutes.
Death Canyon Road and Trailhead will be fully closed from May 1 through November 15, with a delayed opening anticipated into 2027. Visitors planning to access Death Canyon this summer will need to approach from other trailheads.
Teton Park Road
Near the Moose Entrance Station, initial construction for a future roundabout on Teton Park Road will cause some delays this season. A temporary bypass will be built in preparation for the roundabout’s full construction in 2027. The multi-use pathway will remain open throughout, and biking north from Moose on Teton Park Road is a great alternative for reaching destinations like Jenny Lake.
Taggart Lake Trail
The northern segment of the Taggart Lake Trail, between the first junction and the Bradley Trail, will be closed from May 1 through November 15, 2026. The closure allows crews to complete trail repairs, regrading, and accessibility improvements that will make the route more enjoyable for families and visitors with mobility needs.
The Taggart Lake Trailhead and parking lot will remain open and both Taggart and Bradley Lakes will still be accessible via alternate marked trails that add about a mile to the overall route. Cottonwood Creek Picnic Area will also remain open through late summer.
This work is funded by Grand Teton National Park Foundation in partnership with Grand Teton National Park, part of our ongoing commitment to ensuring the park’s most beloved trails are safe, accessible, and built to last.
Mormon Row Historic District
Mormon Row will remain open all season, but visitors should expect to see construction equipment, hear some noise, and encounter localized disruption from mid-June through mid-November. The project expands pedestrian and cyclist access to the area and includes accessibility improvements that support a better experience for all visitors.
This is the final phase of a multiyear project funded by the Grand Teton National Park Foundation.
Teton Park Road (Northern End)
Construction on the northern end of Teton Park Road between Leeks Marina and Lizard Creek Campground will result in nighttime delays of up to one hour between 9:00 PM and 6:00 AM. Daytime travelers should expect delays of up to 15 minutes due to one-lane alternating traffic.
Plan Ahead
While construction can be an inconvenience, each of these projects represents a meaningful investment in the long-term health, accessibility, and safety of Grand Teton National Park. We appreciate your patience as this important work unfolds, and we look forward to welcoming you to the park this season.
