The TMA is a non-profit group dedicated to improving transportation services in, to, and through the Duwamish business community, extending from the professional sports stadiums in the north to King County International Airport in the south.

The TMA can help business owners and managers address individual transportation needs while serving as a community advocate for government projects, issues, and policies impacting the Duwamish business community. Through a unique partnership with Metro, the TMA can also connect businesses with free and low-cost services that encourage employees to ride the bus, join carpools, and use other alternatives to drive alone commuting.

The Duwamish TMA is also able to provide members with a employee transportation program. We will be your ETC, employee transportation coordinator, and do all the paper work necessary to maintain a benefits program.

TMA members are welcome to participate in events where they can get to know key government decision makers and administrators for transportation services.

The TMA operates in partnership with the City of Seattle, the Washington State Department of Transportation, King County Metro, and the Port of Seattle.
