A brief travel closure on the unpaved section of the Moose-Wilson Road in Grand Teton National Park will be in place for about 28 hours, beginning 4 a.m. Wednesday, September 4.
Barring rainy weather or equipment malfunction, the road is scheduled to reopen by 8 a.m. September 5. The temporary closure is scheduled to accommodate dust abatement work, according to a statement released by the park’s public affairs office.
Local residents and park visitors are advised to plan ahead and use an alternate route because this temporary closure prevents the ability to make a ‘through trip’ on the Moose-Wilson Road. This will be the third dust abatement application this summer.
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 in Moose, Wyoming.
To alert travelers of the expected daytime road closure, electronic signs will be placed on Wyoming Highway 390, beginning Tuesday, September 3. 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. Therefore, motorists who drive this portion of the Moose-Wilson Road after it reopens on Thursday may want to rinse off their vehicles to eliminate any residue.
Road work schedules may change, or be delayed, due to weather conditions, equipment malfunction, or other extenuating circumstances.
