Mount Rainier National Park has scheduled a nighttime closure of the Nisqually Road between the Nisqually Entrance and Longmire. On Monday and Tuesday nights, August 4-5, and if necessary Wednesday August 6, no traffic will enter or exit the park via the Nisqually Road between 9:30 pm and 4:30 am.

Visitors are required to use Stevens Canyon Road for any access into or out of the park during the scheduled closure. In the case of an emergency, visitors should dial 911 for immediate assistance.


An underground culvert will be installed where a branch of Tahoma Creek passes beneath the Nisqually Road, near the Westside Road junction. To complete this task as quickly as possible and to minimize the impacts to visitors during this crucial installation, the construction will occur overnight.

The project includes digging a hole across the full width of the road rendering it temporarily impassable, removing the current culvert, and installing a larger culvert in this fish-bearing stream. Access along the Nisqually Road will resume on Tuesday morning following the closure. The road will close again Tuesday and possibly Wednesday at 9:30 pm if more time is needed.

Construction along the Nisqually Road up to Longmire began in March and is expected to continue into September. Daytime delays up to 20-minutes are expected where smaller culverts are installed along the seven miles. Depending on the weather, final paving could begin in early September.

These improvements will preserve the road’s integrity as a popular scenic drive, and provide continued safe access for years to come.
