GRAND TETON NATIONAL PARK — Tourism is starting to pick up, as is construction season in Jackson. Grand Teton National Park (GTNP) is no exception, and will see much more activity and construction-related impacts this year.
The National Park Service (NPS) is set to make some significant infrastructure changes preceding the park’s centennial coming up in 2029, which will impact access in some areas of the park through mid-November.
Projects include re-aligning the Moose-Wilson Road to meet a new Teton Park Roundabout, which will move the park entrance to allow “traffic to transition seamlessly to the Teton Park Road without passing through another entrance station.”
The Death Canyon Trailhead will also be closed for the summer. Death Canyon will be accessible from alternate trailheads, including Granite Canyon and Jackson Hole Mountain Resort.
Work has already begun on the Moose-Wilson Road, which was fully paved in 2023. The road has been closed between Laurance S. Rockefeller Preserve and Moose since May 1 and is expected to reopen with delays from June 20 to Sept. 7. It will close again Sept. 8 to Nov. 15 to complete construction.
Mormon Row Historic District will also remain open for the entirety of the summer. Visitors, however, can expect to see construction vehicles and work as parking lots and designated trails are paved and a designated bus parking lot and restrooms are added.
Other projects in the park include rehabilitation of the northern segment of the Taggart Lake Trail between the first junction and the Bradley Lake Trail, which will be closed through Nov. 15.
To add to the list, visitors can also expect nighttime construction to manage erosion on the Northern Park Road on US89/191/287 throughout the summer. Work will be focused between Leeks Marina and Lizard Creek Campground, and traffic will be controlled by a temporary stoplight alternating one lane of travel.
Locals and visitors to GTNP can follow along with construction updates on the NPS website. Road status updates can be found here.
