Sumner-Buckley Highway East is a 8.5-mile long arterial that connects Bonney Lake (Veterans Memorial Dr E) and Buckley (W Mason Ave). The corridor is a scenic and rural bypass to SR-410, as it connects to the state highway on both ends. The majority of the land along Sumner-Buckley is used for agriculture and farming. The historic Naches Pass Trail also followed what is now Sumner-Buckley Hwy E, and was used by early trappers, traders, Native Americans, settlers, and the military in Pierce County. During the Puget Sound Indian War of 1855-1856, the military travelled this route between Fort Steilacoom and Fort Walla Walla.
The existing roadway surface is the result of a contracted HMA overlay constructed in 1992, and 3/8” bituminous surface treatments applied in 2003 and 2012. The surface condition of this segment of road was most recently rated last year, resulting in an average PSC score of 74.5.
The proposed project will resurface the roadway to provide structural adequacy, and restore the surface condition, by overlaying the roadway with a minimum of 2” of HMA. At the Dingle Basin Bridge No. 33206-A, the existing deck will be repaired with a polyester concrete overlay.
Additionally, roadside safety improvements will be made to existing guardrail in multiple locations within the project limits. Any existing guardrail, transitions, and terminals within the project limits which are Type 1 and do not meet current standards will be removed and replaced with Type 31 guardrail.
