The Trinity Parkway Corridor Major Transportation Investment Study's (MTIS) purpose was to develop a locally-preferred plan of action to solve transportation problems within the Trinity River Corridor in Dallas, and to integrate with community plans and goals for the Trinity River F1oodway, a major open space resource in the city. The stakeholders for this project included community interests (residents, businesses, civic groups, environmental interests and commuters), locally elected officials and involved agencies. The study has been managed by the Texas Department of Transportation and carried out between January 1996 and August 1997.
The Trinity Parkway Corridor study was focused on transportation needs in the T30/I-35E interchange near downtown Dallas, locally knonvn as the "Mixmaster", and the depressed segment of I-30 south of downtown fondly referred to as the "Canyon." The study area was enlarged beyond downtown Dallas to Include a reasonable area of influence of the Canyon and Mixmaster on area transportation facilities.
The Trinity Parkway Corridor study has been closely coordinated with public agencies in the Dallas area, including the City of Dallas, Dallas County, DART, North Central Texas Council of Governments and the Texas Turnpike Authority. Also, the Trinity River Authority, US Army Corps of Engineers, Federal Highway Administration, Federal Transit Administration and TxDOT. Public involvement activities have included four series of public meetings, and monthly meetings with the Community Advisory Work Group (a representative group of involved citizens).
Other public outreach activities comprised of small group presentations, newsletters, posting of project documents at public libraries, a telephone hotline, newspaper advertising and press coverage of study events. The study has been guided by a team of local agencies, acting through political and senior management representation on the Policy Coordination Work Group. This presentation will move through the process from the inception of the study to the recommended plan of action.
