Service Overview



Agency Summary

Mason Transit Authority (MTA) is a nationally recognized small rural public transit system with diverse services that provide our communities with world-class transit.  In addition to serving the Mason County community for 25 years, MTA connects with four area transit systems.  Our regional connections provide access to Grays Harbor Transit, Intercity Transit, Jefferson Transit, Kitsap Transit, Squaxin Island Transit, and Sound Transit, which in turn provides connections to the ferries, Amtrak, and Greyhound service. You can go anywhere from here!!


Funding & revenue is provided to Mason Transit Authority as a public transportation benefit area through local sales tax (6/10 %), transit fares, federal and state grants, as well as contracts for services.  Transit leadership is provided by the Mason Transit Authority Board, a nine-member board made up of local elected officials: three Mason County Commissioners, one City of Shelton Commissioner, and five rotating school district board members.


MTA works with our taxpayers, Mason County, the City of Shelton, local tribal nations, Peninsula Regional Transportation Planning Organization, Lewis Mason Thurston Area Agency of Aging, other social service agencies, schools, local Chambers of Commerce and Economic Development Council, as well as area employers to increase the quality of life in Mason County by meeting the transportation needs of our community.

We operate general services Monday through Saturday. Bus services are not offered on Sunday or major holidays. Check the Rider Alerts page on our website for the most up-to-date schedules and service alerts.


Bus Service Overview

Regular routed and express route bus service is that which is going to the same locations at the same time. Nine routes are offered on weekdays and eight routes on Saturdays.  These routes serve the core areas of Mason County (Shelton, Hoodsport, Union, Allyn, and Belfair), provide express service between Olympia and Bremerton, and make connections to neighboring transit agencies at the Olympia Transit Center, the Bremerton Transportation Center and Brinnon at Triton Cove State Park, which provides access to ferries, AMTRAK and Greyhound services.


Our bus routes operate as a deviated fixed-route service, which allows a limited distance deviation off of the regular bus route. Available on most routes depending on road condition. Call the Customer Service Center a minimum of two (2) hours in advance for this service.


Express service is a bus route that is intended to provide quicker service than normal services between the same two commuter destination points. Express trips operate on a faster schedule by not making as many stops as normal service, and often taking quicker routes, such as along freeways. This service does not make flag stop requests or provide route deviation. An express service is identified by the letter “X” before or after the regular route. For example, Route 6X.

Dial-A-Ride & LINK Service

Dial-A-Ride (DAR) and LINK service is a demand-response service that only travels within Mason County.  “Demand-response” means it’s a non-fixed route that requires advance scheduling by the customer and is a shared ride where trips are generated by said calls from customers.  Typically, the vehicle will be dispatched to pick-up several customers at different pick-up points before taking them to their respective destinations and may even be interrupted en route to these destinations to pick up other customers.


Our schedulers group customers together based on time and space availability.  Our goal is to meet the customers’ needs as best as possible, while still being cost-effective.  DAR and LINK are available to the general public, there is no application or eligibility requirements.  We will refer customers to use routed service first and foremost if it is available and accessible.


Current LINK Service areas:

  • Lake Limerick & Mason Lake
  • Arcadia/Lynch Rd/Totten Shores & Fawn Lake
  • Shorecrest/Timberlakes/Harstine Island/Pickering

Commuter Vanpool Program

A vanpool is a group of five to twelve people who commute to work together in a van provided by MTA. Vanpools generally follow a set schedule and route, but unlike a bus, these are set by the riders themselves. Vanpools must begin or end in Mason County. Individual fares vary based on travel distance, number of riders, and in some instances are paid for through employer commuter reduction programs. Fares cover all gas, maintenance, insurance and even vehicle washing. Whether you’re interested in joining a vanpool or want to start one yourself, we can help you!  Click here to be redirected to Vanpool Program page with more detailed information
