Since 1993, the Washington State Department of Transportation (WSDOT) has met with tribes annually to address mutually identified transportation issues. At the 2003 Tribal/State Transportation meeting the TTPO was formally established.
The purpose of the organization is for tribes to take an active role in statewide transportation planning by providing a forum to discuss and participate in tribal transportation system needs and opportunities.
