Mount Rainier National Park Superintendent Dave Uberuaga, Washington State Department of Transportation and Federal Highway Administration officials announce that the rehabilitation of State Route 123 and SR 410 is scheduled to begin the week of June 16, 2008. Project completion is expected this October.

Approximately 5.8 miles of SR 123 from two miles south of Deer Creek Bridge to the intersection of SR 410 at Cayuse Pass and 1.5 miles of SR 410 from mile north of Cayuse Pass, east towards Chinook Pass to the first major switchback are slated for improvements.

Specific work under this project will include: improving drainage; excavating, stabilizing and reinforcing failing subsurface material; repairing /stabilizing historic rock retaining walls; milling /recycling the asphalt surface as road base; and resurfacing with asphalt. Work also involves replacement of the failing stone /timber fence in the Tipsoo Lake area with a border rock edge that will withstand heavy snow loading experienced in this area and circulation /safety improvements at the Cayuse Pass intersection.

During the summer months, visitors should anticipate 20 minutes delays Mondays through Fridays. After the Labor Day holiday, SR 123 will be closed from 6 a.m. through 5p.m., Mondays through Thursdays until work is completed. Visitors should also anticipate one-lane alternating access on SR 410 at Mile Post 73 (approximately five miles east of Chinook Pass within Wenatchee National Forest) due to damage from last winter’s avalanche activity.

SR 123 serves the east side of the park, extending for approximately 20 miles from the intersection of U.S. 12 to the south to the intersection with SR 410 on the north at Cayuse Pass. SR 410 also serves the east side of the park, extending from SR 167 near Sumner, east 107 miles over the Cascade Range at Chinook Pass to the intersection with U.S. 12, four miles west of Naches. SR 410 is one of five state highways that connect the Puget Sound area with eastern Washington. SR 410 is closed at the park boundary during the winter months, approximately early December to late May.

The Federal Highway Administration awarded the contract to DLM Contracting, Inc. of Bozeman, Montana for $6,072,726.00 on May 16, 2008, and the Notice to Proceed was issued on June 5, 2008.
