The Wyoming Department of Transportation (WYDOT), in partnership with Ames Construction, has postponed the planned closure of Wyoming State Highway 22 (WYO 22) over Teton Pass from June 21 to the weekend of June 28, 2025, due to recent rain and scheduling conflicts. Announced on June 17, 2025, the closure is necessary to complete the final phases of the Big Fill Slide reconstruction project, which addresses a major landslide that damaged the roadway in June 2024.
The closure will begin on Friday, June 27, at 6:00 p.m. and continue through Sunday, June 29, reopening on Monday, June 30, at 6:00 a.m. Crews will work 24 hours a day to mill, grade, place crushed base, pave, and install guardrails and signs along the final stretch of new roadway. During the closure, WYO 22 will be inaccessible to vehicles at Coal Creek Campground on the west side and at the mile marker 7 gate on the east side. Drivers must detour via US 26 through Swan Valley and Snake River Canyon, adding significant travel time.
WYDOT Resident Engineer Bob Hammond explained that recent weather delays and the need to ensure crew readiness prompted the rescheduling. The decision to opt for a weekend closure minimizes disruption for weekday commuters. Bicyclists and recreationalists can still access Coal Creek Campground and the top of Teton Pass from the east side but are urged to avoid descending west toward the construction zone and to remain cautious of heavy truck traffic.
While WYDOT and Ames Construction anticipate completing the work within the weekend, unpredictable weather or other factors could alter the schedule. Drivers are encouraged to sign up for 511 Notify text alerts at 511Notify.wyoroad.info for real-time updates. Additional details on the Big Fill Slide project are available at WYDOT’s media kit at dot.state.wy.us/bigfillslide.

WYDOT reminds drivers to obey all roadside signs, traffic control devices, and closures to ensure safety for workers and travelers. The project, part of a $24.5 million effort awarded in July 2024, aims to restore safe passage over Teton Pass, a vital link between Jackson, Wyoming, and Victor, Idaho.
