Motorists and bicyclists should plan to use an alternate route on October 6 and 7 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 will be the third dust abatement treatment for the 2015 season. An earlier treatment scheduled for September 15 through 17 was postponed due to wet conditions.
For those wishing to reach the Laurance S. Rockefeller Preserve parking lot and trails 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. The Laurance S. Rockefeller Preserve Center is closed for the season.
To alert park visitors and local residents of the scheduled road closure, electronic signs will be placed on Wyoming Highway 390. For travelers heading south to Teton Village from the Moose area, signs will also be placed at the junction with 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.
