Roadwork all summer long in Grand Teton NP

JACKSON HOLE, WYO – Pavement preservation work on US Highway 89 and other areas in Grand Teton National Park are scheduled to begin Thursday, May 16, depending on weather. Friday’s forecast looks to bring a good chance of rain throughout the day, so watch for a change in scheduling.

Travelers should expect up to 15-minute daytime delays as chip-seal activities get underway. Work on US Highway 89 will begin at the park’s southern boundary and continue northbound throughout the year, extending to the south gate of Yellowstone National Park. Roadwork is dependent upon weather and temperature conditions.

The park-wide pavement preservation project will be ongoing throughout summer. Crews hope to be done by the end of September. Visitors will see increased construction signage and equipment staging throughout the park.

The project is funded and managed in partnership with the Federal Lands Highway Program. The contract for the project was awarded to Intermountain Slurry Seal of Salt Lake City, Utah. Activities include patching holes and sealing cracks in the pavement surface, applying a chip seal or micro seal on the road surface, followed by a fog seal to reduce airborne gravel. Striping will be the final action.

The chip-sealing work is a rolling construction operation that will gradually proceed from south to north on US Highway 89. Visitors can expect temporary delays and reduced speed limits in these mobile construction zones. Work at parking lots will be managed by sections so that a portion of the lot will always be accessible.

Chip-sealing is a cost-effective way to provide an improved road surface and preserve the underlying pavement. When proactive preventative maintenance activities are completed on park roads, more serious and costly damage to the pavement structure will be averted.

Roadwork will generally occur between 7am and 8pm, daily, including weekends. No work will be done Saturday through Monday of Memorial Day Weekend, May 25-27; or over the Independence Day holiday, Wednesday through Sunday, July 3-7.
