JACKSON HOLE, Wyo. — Construction of the Moose-Wilson Road in Grand Teton National Park is delayed due to supply chain, staffing shortages and an overwhelmed construction industry locally. The southern portion of the road will open to vehicle traffic Thursday, June 16 at 7am, and will remain open until Monday, July 11 at 7am, when construction is anticipated to resume. Up to 30-minute delays are expected the week of July 5 while equipment is mobilized into the area.
When the Moose-Wilson Road opens
- Parking along the southern portion of the road is prohibited. This includes parking at trailheads as well as horse trailer parking along the road.
- The Granite Canyon Trailhead will remain closed to all access. Winter access will be available from December 2022 to March 2023. Access to the Granite Canyon trail system, including the Valley Trail, is available from Jackson Hole Mountain Resort. Grand Teton is working in partnership with the Resort and Teton Village Association.
When construction of the Moose-Wilson Road resumes
- From July 11 to Labor Day, the southern portion of the Moose-Wilson Road from Granite Canyon Entrance to the Laurance S. Rockefeller Preserve will be closed, except on weekends (7pm Friday to 7am Monday) and federal holidays. Parking along the road is prohibited. The southern portion of the road will be closed entirely after Labor Day.
- The northern section of the road will remain accessible. Access to the Laurance S. Rockefeller Preserve and Death Canyon Trailhead will be available from the north, from Moose, Wyoming, during construction.
Work on the Moose-Wilson Road this spring has included salvaging plants, grading the road, staging materials, and most recently, flying materials over the road to the Phelps Lake outlet bridge.
