Moose-Wilson Road construction on tap for Grand Teton NP

Some road closures to plan around when you visit Grand Teton National Park this summer, as Moose-Wilson Road construction will cause a closure of the road on weekdays.

Public access will be limited to weekends during summer construction activities. Work will be completed in phases, with the first phase implemented in 2022-2023, the second phase in 2024-2025, and additional phases designed and implemented in the future.

Here’s a summary of the Moose-Wilson Road construction this summer:

  • From Memorial Day 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 (7 p.m. Friday to 7 a.m. Monday) and federal holidays. Parking along the road is prohibited. The southern portion of the road will be closed entirely prior to Memorial Day and 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. The Laurance S. Rockefeller Preserve Center opens for summer operations May 29.
  • The Granite Canyon Trailhead will be 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, will be available throughout construction from Jackson Hole Mountain Resort. Grand Teton is working in partnership with the Resort and Teton Village Association to provide information about accessing the southeastern part of the park during construction activities.
  • improvements with the Granite Canyon Entrance including an additional entrance lane to ease backups, improvements at the Granite Canyon Trailhead, including two vault toilets, bench seating, additional parking, improved traffic flow, and decreased roadside parking, improvements with the Poker Flats horse trailer parking area, Kaufmann Creek bridge construction, improved pullouts for vehicles along the road, and new visitor information signage.

Phase 2 is anticipated to begin in 2024 and includes repair to the Death Canyon access road, improvements of the Death Canyon trailhead parking, repair of the Death Canyon Junction trailhead parking area, re-alignment of the north section of the roadway, improvements to the new intersection, and final landscape/reclamation efforts of the former roadway.
