Construction work on the Gros Ventre Roundabout and other safety improvements continue along U.S. Highway 89/26/191 in the southern area of Grand Teton National Park. The project is planned to be completed by the end of November.
Paving of the roundabout area will take place this week, including some night work, followed by traffic restrictions on the Gros Ventre Road. Travelers should respect the speed limit in the area, be alert to changing conditions and follow the directional signing, as well as be prepared for approximately 15-minute daytime delays and 30-minute nighttime delays. These delays are in addition to any that may be encountered with typical summer traffic levels.
Vehicle traffic will be transitioning to a portion of the roundabout and left-hand turns onto and out of the Gros Ventre Road from the highway will be temporarily prohibited beginning later this week.
Access to the Gros Ventre Road, including the community of Kelly and the Gros Ventre Campground, will only be available via a right turn from the highway once traffic has partial access to the roundabout. Highway traffic south bound wishing to access the Gros Ventre Road will be encouraged to travel Antelope Flats Road, or travel through the roundabout intersection and detour approximately two miles further south at the park entrance sign pull-through area to turn around. Highway signs will alert traffic to this temporary detour and alternate route. This right-turn only restriction will be removed once the entire roundabout is accessible to traffic by late September.
The temporary pathway for bicyclists and hikers will remain available, in its current design, until the final alignment of the road and roundabout are completed. Pathway users should follow all signs and use caution in the construction area.
During this construction phase, restrictions are in place for oversized vehicles greater than 10 feet wide and more than 81 feet in length. For more information about this load restriction visit .
The construction schedule is subject to change due to weather conditions and other factors. Updates will be communicated via roadside signs, park road information line (307.739.3682), park website (), and park social media (@GrandTetonNPS on Facebook and Twitter).
