Some temporary road closures will take place after Labor Day in Grand Teton National Park as construction and road improvements projects get underway.
The southern portion of the Moose-Wilson Road from Granite Canyon Entrance to the Laurance S. Rockefeller Preserve will close to all access the day after Labor Day, September 6. This section of road will reopen to winter activity in December, through March 2023.
The northern section of the road will remain open to the Laurance S. Rockefeller Preserve and Death Canyon Trailhead from the north, via Moose, WY.
The park will be working with Jackson Hole Mountain Resort and Teton Village Association to provide access to trails at the Granite Canyon Trailhead, including Granite Canyon, Marion Lake, and the Teton Crest Trail.
To access park trails from Teton Village, park in the Ranch Lot and walk or take the shuttle bus to the base area.
The Jackson Lake Dam Boat Launch area in Grand Teton National Park -located below the dam on the north side- will close to all access, including boating, fishing, and parking, beginning September 6. Work will continue into the spring of 2023 for this multi-year project to improve river access points along the Snake River.
The Jenny Lake One-way Scenic Drive will be temporarily closed September 12-16 while road striping operations occur to improve cyclist safety in the area. The work is contingent on dry weather and closure dates may change. New road signs are also planned to be installed this fall.
The access road to the Laurance S. Rockefeller Preserve is tentatively planned to temporarily close September 26-30 to overlay the roadway with new asphalt to repair the existing asphalt surface.
Signal Mountain Summit Road will be temporarily closed September 14. The closure will begin at 8 a.m. to allow safe transport of a new radio tower to the top of Signal Mountain.
Additionally, drivers may encounter minor delays as work occurs on the Gros Ventre Roundabout and along Highway 26/89/191 in Grand Teton throughout the fall. Crews are installing new lighting in the roundabout area as well as two winter gates along the highway near Moose and Moran.
