Road Construction Scheduled for 2010 Season

May 3, 2010
The official summer season in Grand Teton National Park and the John D. Rockefeller, Jr. Memorial Parkway generally begins with the May 1st opening of the Teton Park Road and Moose-Wilson Road to vehicle traffic. The arrival of summer also means that road construction projects resume or start anew throughout the park and parkway.

Of note, the access road leading to the Laurance S. Rockefeller Preserve from the Moose-Wilson Road, as well as the parking lot, will remain closed to public entry until the gravel surfaces can sufficiently dry and harden to handle vehicles. Parking along the Moose-Wilson Road within a mile of the Preserve entrance gate is not allowed, so hikers wishing to reach Preserve trails will need to temporarily use the parking area for Granite Canyon trailhead.

The multi-phase North Park Road project from Lizard Creek Campground to Flagg Ranch Resort will begin again, resulting in
30-minute delays weekdays through July 15. There may be some weekend work taking place on this road project.

An asphalt overlay project on the Teton Park Road from Jackson Lake Junction to North Jenny Lake Junction has already begun and delays of up to 30 minutes are expected from mid May through the month of August. The Signal Mountain boat ramp and access road will also receive an asphalt overlay, resulting in 30-minute delays through the month of August.

The five-mile Signal Mountain Summit Road will be closed for road work from Monday through Thursday—but open to vehicles on Friday, Saturday and Sunday—during the month of June.

When weather permits during May, and continuing through early June, Highway 26/89/191 will be striped from the park’s south boundary to Cunningham Cabin. All other roads and parking areas in the southern portion of the park, including South Jenny Lake parking area, will also be striped during this time. In addition, the Snake River Bridge at Moose will be painted during May and early June. These road and bridge projects may cause 15-minute delays.

Finally, the Antelope Flats Road from Highway 26/89/191 to Mormon Row Road will receive an asphalt overlay in late July, resulting in
15-minute delays.
