Slide Repair Project to Start on Old Hwy 99 North of Tenino
Motorists who use Old Hwy 99 SE between Tenino and Waldrick Rd SE will be impacted

OLYMPIA / TENINO - Motorists who use the old Pacific Highway near Tenino will be impacted by a road project. A slide repair project approximately 1.5 miles north of Tenino will begin mid-September. Thurston County Commissioners have approved a contract with Prospect Construction, Inc. of Puyallup, WA at their bid price of $461,832.80.

The landslide occurred in late November 2015 and resulted in approximately 200 feet of roadway shoulder cracking and slumping. The purpose of this project is to repair the damaged areas of the shoulder and roadway fills, and reduce the potential for future sliding.

Major work includes construction of an approximately 165 feet long soldier pile wall using 37 feet long piles driven 30 feet into the ground, reconstruction of 200 feet of the southbound lane, installation of new guardrail and other associated work.

For this slide repair project, there will be at least one lane of traffic open at all times. Traffic will alternate by use of a temporary signal. Typical delays are anticipated to be five minutes or less, but may exceed that time on rare occasions. Drivers may want to avoid the area by using other routes. The project is scheduled to start mid-September and should be complete by early November.

Senior Civil Engineer Matt Unzelman says, "Installation of a wall and reconstruction of a damaged lane is necessary to help prevent future slides at the site. Full closure of one lane is the only way to physically complete the work. Drivers can travel on McDuff Rd approximately 2 miles outside of Tenino to get an idea of how the temporary signal may impact their daily commute."
