MOOSE, WY \u2014 The unpaved section of the Moose-Wilson Road in Grand Teton National Park will be temporarily closed for road grading beginning at 8 p.m. Tuesday and will reopen by 6 a.m. tomorrow. If the road maintenance work is not completed during this one night, the road will also be closed the following night during the same timeframe. These night grading operations are in addition to dust abatement treatments which take place throughout the summer. The additional grading is necessary between the dust abatement applications to maintain the road surface in light of increased daily traffic. During the overnight closure, park visitors should plan to use an alternate route as this temporary closure will prevent making a \u2018through trip\u2019 on the Moose-Wilson Road. The closure will extend from the Granite Canyon Entrance Station to a gate south of the Laurance S. Rockefeller Preserve Center. Electronic signs will be placed on Wyoming Highway 390 and near Moose to alert park visitors and local residents of the scheduled road closure. In addition, the final phase of emergency repairs related to the June 2017 washout of the Gros Ventre Road began Monday. Traffic will be reduced to one lane of travel and traffic delays associated with the Gros Ventre Road repair project will be limited to 15 minutes between 5 a.m. and 9 p.m. No weekend work is scheduled at this time. Roadwork schedules may change, or be delayed, due to weather conditions, equipment malfunction, or other extenuating circumstances.
