The dust abatement application project on the Moose-Wilson Road is rescheduled to next week, September 20-21, due to forecasted weather conditions. Originally planned for this week, a brief travel closure will be in place for about 48 hours, beginning 4 a.m. Tuesday, September 20, on the unpaved section of the Moose-Wilson Road in Grand Teton National Park. The road will reopen by 8 a.m. Thursday, September 22.
Motorists and bicyclists should plan to use an alternate route on September 13-14 as this temporary closure will prevent making a 'through trip' on the Moose-Wilson Road from Granite Canyon Entrance Station to the Teton Park Road at Moose, Wyoming. This is the second of three scheduled dust abatement treatments for the 2016 season.
For those wishing to reach the Laurance S. Rockefeller Preserve or Death Canyon Trailhead, access will be possible by heading south from the Teton Park Road junction near the Craig Thomas Discovery and Visitor Center. Those wishing to reach the Granite Canyon Trailhead may do so by heading north from the Granite Entrance Station.
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 to reach Granite Canyon Trailhead during the treatment or after the road 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.
