A brief travel closure will be in effect on the unpaved section of the Moose-Wilson Road in Grand Teton National Park for about 28 hours, beginning at 4 a.m. on Wednesday, July 11. The road is scheduled to reopen by 8 a.m. on Thursday, July 12, barring equipment malfunction or rainy weather. The temporary closure is scheduled to accommodate dust abatement work; this is the second application this summer.

Road crews will complete this project in the shortest time possible. 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.

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, July 10. 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. 

Roadwork schedules may change, or be delayed, due to weather conditions, equipment malfunction, or other extenuating circumstances.

Did You Know?

Did you know that lodgepole pine trees grow on glacial moraines in Jackson Hole? Glacial moraines are ridges of rocky debris left behind as Ice Age glaciers melted. The soil on these ridges retains moisture and is more hospitable to trees than the cobbly, porous soil on the outwash plain.
