Speed Limit Information

To request speed limit revision in your area, you must complete a service request. Staff will then contact you for further details. The Board of County Commissioners sets the final decision to change the speed limit. Note: speed limits in school zones and residential areas are set by county code and cannot be changed.

Speed Limit revisions are presented yearly 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 wheeled ATVs to travel on county roads with a maximum speed limit of 35 MPH by licensed drivers over the age of 16. You can find the roads here.

Use the link below for more information about how speed limits are set.

Thurston County Public Works ADA Program

Pedestrian travel is a vital transportation mode. Nearly everyone uses it 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) require 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 with disabilities. This plan shows improvements that have been made and 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.
