CASPER, Wyo.– Construction of the Moose-Wilson Highway will resume at 7 a.m. Monday, July 11 in Grand Teton National Park.

Supply chain issues and staffing shortages affecting the construction industry have caused delays to the project, the National Park Service said in a June news release.

With construction resuming on Monday, drivers should be aware of some road closures, the NPS press release said Friday.

The southern portion of Moose-Wilson Road between the entrance to Granite Canyon and the Laurance S. Rockefeller Preserve will be closed weekdays from July 11 through the Friday before Labor Day. This section will be open on weekends from Friday 7 p.m. to Monday 7 a.m., according to the NPS. The road will also be open on Labor Day. Parking along the road, including at the start of the trails, is prohibited. After Labor Day, the southern portion of the Moose-Wilson will be completely closed.

“The Granite Canyon Trailhead will remain closed to all access,” the NPS said. “Winter access will be available from December 2022 through March 2023. Access to the Granite Canyon trail system, including the Valley Trail, is available from Jackson Hole Mountain Resort. Grand Teton works in partnership with the Resort and Teton Village Association.

The northern section of the Moose-Wilson Highway will remain open while the southern section is constructed, providing access to the Laurance S. Rockefeller Preserve and the Death Canyon Trailhead.

“Grand Teton National Park reminds visitors to plan ahead, especially during the busy summer months. To check the status of the Moose-Wilson road, visit Grand Teton’s live road condition map at or call 307-739-3682,” the statement read. “The park will continue to use Twitter to communicate Moose-Wilson Road weekend openings and closings to the public when construction resumes. Follow Grand Teton on Twitter @GrandTetonNPS.

“Park staff will assess construction impacts for 2023 and share more with the public in the fall. For more information about the project, visit the park’s website at
