A culvert replacement project will close SR 123 at Cayuse Pass starting on Monday morning.

Drivers planning to visit the southeast side of Mount Rainier will need to use the entrance off US 12 next week while crews replace a failed culvert under State Route 123.

Beginning at 7 a.m. Monday, Sept. 17 crews working for Mount Rainier National Park will close a seven mile stretch of SR 123 from just north of the Shriner Peak trailhead to the Cayuse Pass summit. The highway is scheduled to reopen by 5 p.m. Tuesday, Sept. 18. State Route 410 which intersects with SR 123 at the Cayuse Pass summit will not be affected by this closure.

During the temporary closure, drivers can still visit the park’s southeast attractions by traveling on US 12 and then north on SR 123 to reach the Stevens Canyon entrance.

More information on park access and the culvert replacement project can be found on the Mount Rainier National Park website.
