State Highway Road Construction 8/19 to 8/25

The following is a summary of road construction and maintenance scheduled on state highways around Mason County and adjacent areas from August 19, 2018 to August 25, 2018.


US 101 – Lynch Road – Safety Improvements
US 101 Region: Olympic County: Mason Location: Milepost(s)  352.5
Description: Crews working for WSDOT will begin safety related enhancements at this intersection. The overarching goal is to help reduce the potential for crashes while keeping people moving.

Crews will make the following improvements:
• build a 1,200-foot-long acceleration lane for Lynch Road drivers merging onto northbound US 101 (heading toward Shelton);
• build a 1,140-foot-long acceleration lane for Lynch Road drivers merging onto southbound US 101 (heading toward Olympia).
The acceleration lanes will enhance drivers’ ability to reach highway speeds before merging onto the highway.

Crews also will make modifications to the roadway to help increase sight distance for Lynch Road drivers merging onto southbound US 101. Please see the attachment that provides an idea of what crews will build

Work Schedule: Work will begin Monday, Aug. 20 and be completed by early fall. During construction, drivers can expect day and night single-lane closures. Drivers can also expect night closures of the highway median. Signed detours will be provided via the first Shelton exit (SR 3) and Kamilche.

  • Leave room between you and the car ahead of you – Most work zone accidents involve someone
  •  running into the car ahead of them. Drive defensively – be aware of what is happening around you.
  • Merge before you reach the work zone.
