Tuolumne County Transportation Council

The Tuolumne County Transportation Council (TCTC) is responsible for developing transportation improvements that reflect the needs, concerns and actions of all the agencies (including Tribal Governments) involved in the Tuolumne County region, while contributing to the region's mobility needs, economic health, and environmental quality.


Here, you can find TCTC's minutes, forms, agendas, and related documents/links. We also manage the resources of the Tuolumne County Transportation Agency and associated advisory councils, which all play a role in the future of transportation in Tuolumne County.
