Upcoming construction changes at Taggart Lake Trailhead, Moose-Wilson Road and Teton Park Road

Grand Teton National Park is entering the next phase of several major construction projects, bringing changes to visitor access at Taggart Lake Trailhead and along the Moose-Wilson Road corridor. Visitors should plan ahead for changing conditions, follow posted closures and allow additional time when traveling through construction areas.

“We know construction can change the way people experience some of their favorite places in the park, especially during the busy summer season,” said Superintendent Chip Jenkins. “We appreciate visitors’ patience and cooperation as crews work to improve trails, roads and facilities while protecting the resources that makes this place special.”

Taggart Lake Trailhead area

Construction continues at the Taggart Lake Trailhead and along the Taggart Lake Trail as part of a multi-year project to improve access, address erosion and protect the heavily visited area. As part of the project, Cottonwood Creek picnic area will close for construction in mid-August. Visitors should follow posted signs and stay out of active construction zones.

The Taggart Lake Trailhead and parking lot remain open, but visitors should expect construction activity and changing conditions in the area. The northern portion of the Taggart Lake Trail remains closed for reconstruction. Taggart Lake can still be reached using the southern route, which is longer and steeper—about 4.25 miles roundtrip.

The project will ultimately provide a renewed Taggart Lake Trail and Trailhead, including improved accessibility, a redesigned trailhead with educational signage to encourage responsible recreation, restrooms, a water bottle filling station, and a larger parking lot to accommodate increased use. The project is supported through a partnership between Grand Teton National Park and the Grand Teton National Park Foundation.

Teton Park Road Roundabout bypass

Construction of a bypass for the future Teton Park Road Roundabout near Moose will begin the week of August 24 and is expected to continue for about two weeks.

During construction, vehicle traffic will be reduced to one lane and controlled by flaggers. Visitors should expect delays of up to 20 minutes, not including wait times at the Moose Entrance Station.

Menors Ferry Road is anticipated to be closed during construction. Pathways cyclists should follow posted signs and expect to use the road shoulder through the construction area, which includes some temporarily unpaved areas.

The bypass is expected to be paved at the end of September.

Moose-Wilson Road between Moose and LSRP closes September 7

The Moose-Wilson Road between the Laurance S. Rockefeller Preserve and Moose is currently open to through traffic, with intermittent delays of 45 minutes or longer possible as construction continues.

The road between Moose and the LSRP will close to motor vehicle and bicycle traffic at the end of the day September 7 as construction resumes in the corridor. The closure is scheduled to continue through November 15.

After November 15, the corridor will transition to seasonal winter recreation use as conditions allow. Visitors should check current road and trail conditions before traveling to the area.

Death Canyon Road and Death Canyon Trailhead, accessed from the Moose-Wilson Road, remain closed for construction throughout the 2026 season.

Current road, trail and construction information is available on the park's road construction webpage and current conditions webpage.

Rising more than 7000 feet above Jackson Hole, the majestic mountains of Grand Teton National Park provide one of the most dramatic landscapes in the world. With more than 240 miles of trails meandering throughout this park, how will you find and choose the most scenic and rewarding hikes?

Exploring Grand Teton National Park takes all the guesswork out by focusing on the most amazing hikes, and provides you with handpicked recommendations that will allow you to make the most of your trip to Grand Teton:

On this date in hiking history: William O. Douglas begins his 22-mile hike to protest an extension of Highway 101

On this date in 1958, U.S. Supreme Court Justice William O. Douglas led a 22-mile trek along the Olympic coast in Washington, just west of Olympic National Park, to protest a proposed extension of Highway 101. This backpacking trip along the rugged coast took three days to complete, but was successful in accomplishing the goal of the roughly 70 participants.

Here’s a pretty cool documentary film of Douglas’s historic hike – both for its historical significance, and the scenery:

Record of Decision amendment signed for Moose-Wilson Road

The National Park Service has approved an amendment to the Record of Decision for the Moose-Wilson Corridor Comprehensive Management Plan in Grand Teton National Park. Acting Intermountain Regional Director Bert Frost signed the ROD amendment on Aug. 14, 2026.

"We remain committed to providing appropriate recreational opportunities while maintaining the natural and cultural resources that sustain a healthy, functioning ecosystem," said Grand Teton National Park Superintendent Chip Jenkins. "We are balancing visitor access with long-term stewardship."

A 2016 Final Environmental Impact Statement evaluated multiple alternatives for managing the Moose-Wilson Corridor. Following a re-evaluation of that analysis, the NPS determined the effects of the amended decision are similar to those analyzed in the 2016 EIS. The ROD amendment incorporates two elements previously analyzed under Alternative D of the 2016 Final EIS: (1) construction of a separated multiuse pathway along the corridor and (2) realignment of a segment of Moose-Wilson Road between Sawmill Ponds and Death Canyon Road. All other improvements from the 2016 ROD remain unchanged.

The amended decision also includes refinement and mitigation measures to reduce impacts to wildlife, wetlands and cultural resources, including locating the pathway as close to the roadway as practicable to minimize disturbance.

In accordance with the National Historic Preservation Act, the NPS worked with the Wyoming State Historic Preservation Officer, federally recognized Tribes and other consulting parties to develop a Programmatic Agreement. The park also coordinated with the U.S. Fish and Wildlife Service to evaluate potential impacts on wetlands and prepare a Wetlands Statement of Findings.

With the amended decision now in place, the park will move into implementation by developing a project timeline and initiating topographic surveys within the Moose-Wilson corridor.

The ROD amendment, the Programmatic Agreement, Wetlands Statement of Findings, Biological Opinion and public comments are available on the project website.

On this date in hiking history: The final link in the Appalachian Trail is completed

On this date in 1937, a Civilian Conservation Corps crew finished construction on a two-mile section of the Appalachian Trail between Spaulding and Sugarloaf Mountains in Maine, thus connecting the final link along the entire trail. At that time, the footpath traveled roughly 2025 miles, from Mount Oglethorpe in Georgia to Mount Katahdin in Maine. However, the Appalachian Trail Conservancy website notes that the route is constantly changing, and estimates that 99% of it has been rebuilt or relocated since its initial completion, including the reroute to its current southern terminus at Springer Mountain. As you can see in this photo, women were active in building the trail, especially before the CCC became involved in 1933:

Here’s the Bates Outing Club conducting maintenance work on the Appalachian Trail, circa 1939. According to the video description, “The black liquid they're smearing on their faces and arms at the 42-second mark is probably pine-tar fly dope (nasty stuff!).”

On this date in hiking history: Two grizzly bear attacks in Glacier National Park

On this date in 1967 the unthinkable occurred. Two women, in separate incidents, were killed by grizzly bears while backpacking in Glacier National Park. The incidents were detailed in the best-selling book, Night of the Grizzlies, by Jack Olsen. Fifty years after the events of that night, PBS broadcast an outstanding documentary with the same name. As a hiker, this can be a little difficult to watch at times:
