To accommodate a dust abatement application, a brief travel closure will be in place for about 48 hours, beginning 4 a.m. Tuesday, August 4, on the unpaved section of the Moose-Wilson Road in Grand Teton National Park. The road will reopen by 8 a.m. Thursday, August 6.
For those wishing to reach the Laurance S. Rockefeller Preserve or Death Canyon Trailhead, access will only be possible by heading south from the Teton Park Road junction near the Craig Thomas Discovery and Visitor Center.
To alert park visitors and local residents of the scheduled road closure, electronic signs will be placed on Wyoming Highway 390, beginning Monday, June 8. For travelers heading south to Teton Village from the Moose area, signs will also be placed at 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.
