Road maintenance on Granite Creek Road
Short closure on Monday, July 13th for surface treatment
by Bridger-Teton National Forest
July 1, 2026
The Bridger-Teton National Forest will begin road maintenance work on the Granite Creek Road beginning the week of July 1, with work anticipated to be completed by July 14.
The project aims to provide a safer transportation system and protect existing infrastructure. This will be accomplished by improving the driving surface through surface blading, cleaning ditches and culverts and adding new surface course material—a fresh layer of crushed gravel that restores and improves the road surface. The Bridger-Teton Roads Crew will apply a magnesium chloride product to the road surface, which will help to reduce dust and protect loss of aggregate in the surface course material.
Motorists can expect numerous large haul trucks and other heavy equipment operating on Granite Creek Road (NFSR 30500) from approximately milepost 0.0 to milepost 7.5. The Forest will conduct general road maintenance through July 14, with aggregate deliveries beginning July 6. The road will close to traffic from 9 a.m. to approximately 3 p.m. on July 13, to allow for a magnesium chloride application.
The product used for dust abatement is a slurry of magnesium chloride, the same product that is used to treat dirt roads throughout Wyoming. This product coats the road surface, but it can also adhere to the undercarriage of vehicles before it fully cures. Motorists who drive the treated portion of Granite Creek Road after it reopens may want to rinse off their vehicles to eliminate any residue.
The public should use extra caution when driving in the area. When passing heavy equipment, ensure operators can see your vehicle before proceeding and allow extra space around construction traffic. The public can expect intermittent traffic delays and should follow all posted signage and traffic restrictions in the area.
The Bridger-Teton National Forest appreciates the public’s cooperation and understanding. These temporary disruptions will result in improved road conditions and better recreational access.
The Granite Creek Road Maintenance Project is in partnership with The Hawken Ranch. The Bridger-Teton Roads Crew is providing maintenance, grading and gravel spreading, and The Hawken Ranch is contributing with material acquisition and supply, including aggregate gravel and magnesium chloride.
Roadwork schedules may change, or be delayed, due to weather conditions, equipment malfunction, or other extenuating circumstances.
