Intermittent Jackson Lake Dam closures start next week

MOOSE, Wyo. —Teton Park Road across the Jackson Lake Dam in Grand Teton National Park will close intermittently beginning Tuesday, Sept. 24 for crane work.

The Bureau of Reclamation Upper Snake Field Office will be conducting dam work until October 25. During that time, the road over the dam will close on certain weekdays for two-four hours at a time.

Crane work will take place to set and move the bulkhead gate to inspect and perform maintenance work on multiple reservoir release gates at the Jackson Lake Dam.

Closures will occur on the Teton Park Road across Jackson Lake Dam between 9 a.m. and 4 p.m., Monday through Friday for a period of up to four hours for each closure. No evening or weekend work is planned at this time.

Tentative Schedule (subject to change):

Tuesday September 24
10 a.m. to 2 p.m.
Tuesday October 1
10 a.m. to 2 p.m.
Monday October 7
11 a.m to 3 p.m.

11 a.m. to 3 p.m.
Tuesday October 15
11 a.m to 3 p.m.
Wednesday October 16
11 a.m. to 3 p.m.

During this time, travelers will not be able to make a through-trip on the Teton Park Road. Those wishing to access the northern part of Grand Teton or Yellowstone National Park may want to take U.S. Highway 89/191/287. Access to the Snake River, including the boat launch and fishing area below the dam will be available north of Jackson Lake Dam during this time.

Message boards advising visitors of the closures will be operational 24 hours in advance, staged at Jackson Lake Junction and near Signal Mountain Lodge. Flaggers will staff hard closures north of Jackson Lake Dam and south of Catholic Bay Picnic Area.

Further information about this maintenance work can be obtained from the Bureau of Reclamation’s Upper Snake Field Office by contacting Supervisory Civil Engineer Keith Brooks at 208-678-0461.

Work schedules may change, or be delayed, due to weather conditions, equipment malfunction, or other extenuating circumstances.
