The Utah Department of Transportation partially closed the seasonal pass at 2 p.m. Tuesday, Nov. 7.
The closure is from the state Route 190 winter gate near Brighton to the intersection of state Route 224 and Pine Canyon Road. It is still possible to drive between Park City and Heber City on 224 and Pine Canyon.
UDOT Region 2 spokesperson Kylar Sharp said there's no sure time when the pass will close fully. There's no estimated time when Mirror Lake Highway will close for the winter either.
When Guardsman closes fully for the winter, it won’t reopen until spring 2024. In the meantime, the Bonanza Flat area will be accessible by snowmobile, snowshoe and skis.
Park City debuted a winter Transit to Trails program last year, which took recreationists up to groomed Nordic trails.
Park City Trails and Open Space program manager Heinrich Deters said the city has the budget and contractors in place to do winter Transit to Trails again this year, but there isn't likely enough snow in Bonanza Flat to groom just yet. Whether the program will officially return is pending conditions and final approval.
This is a developing story.
