The unpaved section of the Moose-Wilson Road in Grand Teton National Park will be temporarily closed for dust abatement starting at 4 a.m. Tuesday, June 15 and reopening by 8 a.m. Thursday, June 17. This routine dust abatement application happens several times during the summer on the approximately one-mile of unpaved section of the seven-mile road.
During the dust abatement application June 15-17, motorists and bicyclists should plan to use an alternate route as this temporary closure will prevent making a ‘through trip’ on the Moose-Wilson Road between the Granite Canyon Entrance Station and the Teton Park Road at Moose, Wyoming.
For those wishing to reach the Laurance S. Rockefeller Preserve parking area or Death Canyon trailhead, access will be possible by traveling south from the Teton Park Road Junction near the Craig Thomas Discovery and Visitor Center.
Electronic signs will be placed on Wyoming Highway 390 to alert park visitors and local residents of the scheduled road closure. For travelers heading south to Teton Village from the Moose area, signs will also be placed near the junction of the Teton Park Road.
The product used for dust abatement is a slurry of magnesium chloride, the same product that is used to treat dirt roads in and around Jackson Hole. This product coats the road surface, but it can also adhere to the undercarriage of vehicles. Motorists who drive the unpaved portion of the Moose-Wilson Road after it reopens on Thursday may want to rinse off their vehicles to eliminate any residue.
Roadwork schedules may change, or be delayed, due to weather conditions, equipment malfunction, or other extenuating circumstances.
