On Wednesday, March 16, 2016 Grand Teton National Park road crews will begin their annual spring plowing of the Teton Park Road from Taggart Lake trailhead to Signal Mountain Lodge. As plowing operations get underway, over snow access and recreation on this section of road will cease for the season. Visitors may continue to use other areas for skate-skiing, cross-country skiing, and snowshoeing until conditions are no longer favorable.
For safety reasons, visitors may not access the section of Teton Park Road between Taggart Lake trailhead and Signal Mountain Lodge beginning on March 16. Rotary snow removal equipment and plows may be working at any time, and the roadway is therefore closed to all users at all times until further notice. Park rangers will enforce the temporary closure to ensure safe conditions for plow operators and visitors. Skiers and snowshoers using areas adjacent to the roadway are cautioned to avoid the arc of snow being blown from the rotary equipment because pieces of ice and gravel can be thrown great distances.
Depending on weather, snow conditions and plowing progress, the roadway may become accessible to springtime activities such as cycling, roller skating, skateboarding, roller skiing, walking, jogging, and leashed pet-walking by late-March or early-April. This change in road status will be announced and signs posted at the road gates will be updated as appropriate. The road will open to vehicle traffic on Sunday, May 1, 2016.
Other park roads such as Moose-Wilson Road, Signal Mountain Summit Road, Antelope Flats Road, River Road, East Boundary Road, Mormon Row Road, Two Ocean Road, and Grassy Lake Road remain closed when posted or gated in the spring. The opening date of these roads varies from year to year and is dependent on weather, snow conditions, plowing progress, wildlife activity, and road conditions.
The paved multi-use pathways in the park are open whenever they are predominately free of snow and ice.
