Moose-Wilson Road

Bike or auto trips all the way through the Moose-Wilson Road in Grand Teton National Park won't be possible over the next couple of days as the park service performs seasonal maintenance work.

A section of the southern, dirt portion of the scenic drive will be temporarily closed for a routine dust abatement application beginning this morning at 4 (Tuesday, Sept. 14). The road section is scheduled to reopen by 8 a.m. Thursday (Sept. 16). 

"During the dust abatement application, motorists and bicyclists should plan to use an alternate route as this temporary closure will prevent making a ‘through trip’ on the Moose-Wilson Road between the Granite Canyon Entrance Station and the Teton Park Road at Moose, Wyoming," park officials noted.

For those wishing to reach the Laurance S. Rockefeller Preserve parking area or Death Canyon trailhead, access will be possible by traveling south from Moose near the Craig Thomas Discovery and Visitor Center.

Grand Teton National Park will place electronic signs on Wyoming Highway 390 to alert visitors and residents of the 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. The 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," park officials said.

Officials cautioned that roadwork schedules can always change, or be delayed, due to weather conditions or other extenuating circumstances.
