Speed Limit Information
To request speed limit revision in your area, you'll need to fill out a service request. Staff will then contact you for further detail. The final decision to change a speed limit is set by the Board of County Commissioners. Note: speed limits in school zones and residential areas are set by county code and cannot be changed.
Speed Limit revisions are presented once a year to the Board of County Commissioners (BoCC) for consideration and adoption. Any potential revisions received after March 31 will be held until the next calendar year for presentation to the BoCC.
Pursuant to RCW 46.09.455, the Board of County Commissioners passed an ordinance allowing for the travel of wheeled ATVs (WATV) on county roads with maximum speed limit of 35 MPH, by licensed drivers over the age of 16. You can find the roads here.

Thurston County Public Works ADA Program
Pedestrian travel is a vital transportation mode. It is used by nearly everyone and is a critical link to everyday life for many. Section 504 of the Rehabilitation Act and the Americans with Disabilities Act of 1990 (ADA) requires government agencies to design, construct, retrofit, and maintain infrastructure that allows access for persons with disabilities or limited mobility.
Public Works has developed a transportation plan to improve policies and procedures, road standards, and roadway features such as sidewalks and curb ramps for people living with disabilities. This plan shows improvements which have been made, places needing further improvements and outlines a timeline for future projects. Areas for improvement in the new plan include:
- How we respond to requests and design of traffic signals
- Updating ADA standards for county roads
- Adding curb ramps, sidewalks, and pedestrian features to road standards
Funding Sources for ADA Projects
Planned ADA projects can be funded through the following sources.
- County Road Fund
- WSDOT Pedestrian & Bicycle Program
- Transportation Improvement Board Sidewalk Program
- WSDOT Safe Routes to School Program
- Surface Transportation Block Grant (STBG)
