State Route 123 (SR 123) Rehabilitation

SR 123 travels north-south along the east side of the park from the southeast entrance near Packwood, WA, to the junction with SR 410 at Cayuse Pass. The rehabilitation project will work on a 2.8 mile section of SR 123 from Laughingwater Creek Bridge (milepost 2.5) to Panther Creek Bridge (milepost 5.2). The project will replace substrate to level the road, rehabilitate ditches, and replace/upsize 18 culverts.
