MOOSE, Wyo. — Construction projects on sections of the Teton Crest Trail will cause intermittent 30-minute closures, Grand Teton National park announced today.

Closures will occur between July 22-27 and Aug. 5-10 on a section of the trail near the summit of Paintbrush Divide. Hikers should expect delays in both directions.

According to the park, the closures are based on safety precautions. Loose materials such as rocks and gravel may be moved downhill during construction. The closures will allow uninterrupted work to be completed and extra time to clear the trail of any hazards.

Work on Hurrican Pass is also underway this summer. Work began last summer on the highly trafficked portion of the trail but no delays will be needed.

Paintbrush Divide is the highest point along the Teton Crest Trail at 10,700 feet/3,261 meters in elevation. The eastern slope is a scree slope and over time, water flow from melting snow and yearly visitor use has eroded and shifted the trail. The trail damage now poses safety hazards to hikers.
