 A brief travel closure on the unpaved section of the Moose-Wilson Road will be in place for about 48 hours, beginning 4 a.m. Tuesday, July 22, to accommodate a dust abatement application. The road will reopen by 8 a.m. Thursday, July 24.

Park visitors and local residents are advised to use an alternate route on July 22 and July 23 as the 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 second dust abatement application this summer, with one more applications planned for early September.

For those wishing to reach the Laurance S. Rockefeller Preserve or Death Canyon trailhead, access will be possible by driving south from the Teton Park Road junction adjacent to the Craig Thomas Discovery and Visitor Center. 

To alert travelers of the expected road closure, electronic signs will be placed on Wyoming Highway 390, beginning Monday, July 21. For motorists heading south to Teton Village from Moose, 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.
