A culvert replacement project on Tilley Rd SW approximately 2.5 miles north of Old Hwy 99 SE will begin mid-September. Thurston County Commissioners have approved a contract with Active Construction Inc. of Tacoma, WA at their bid price of $434,756.39.
Major work includes installation of an approximately 51 feet long by 11 feet wide pipe arch culvert, realignment and reconstruction of 350 feet of roadway, new guardrail, and more. After paving is completed, crews will install new traffic markings and striping.
Construction Manager Brandon Hicks says, "We apologize for the frustrations this may cause many local residents that use Tilly Rd between Olympia and Tenino. Especially, since drivers are currently being detoured as part of a separate WSDOT SR 121-Blooms Ditch Project which is just 3.8 miles north of our project on Tilley Rd."
Hicks says, "The culvert replacement project is necessary to help alleviate historical flooding at the site and improve fish passage. Similar environmental restrictions apply to this project as they do to the current WSDOT project and we could not schedule it differently."
For the culvert replacement project, there will be at least one lane of traffic remaining open at all times. Traffic will alternate by use of a temporary signal. Typical delays are anticipated to be five minutes or less, but delays up to 15 minutes may occur on occasion or during heavy traffic periods. Drivers may also want to avoid the area by using other routes.
The Tilley Curve Culvert Replacement project is scheduled to start mid-September and may be completed by late October. Most work will be conducted during daylight hours Monday through Friday. One lane alternating signal control will be in place during daylight hours through the duration of the project, and day and night for at least a two week period in the middle of the project.
