Project Overview
The proposed TTC-35 corridor generally parallels I-35. The initial study area is approximately 600 miles long, extending from north of Dallas/Fort Worth to Mexico.
Environmental Studies and Maps
The environmental studies for TTC-35 will comply with the National Environmental Policy Act of 1969 (NEPA). These studies will be used to narrow the project study area and determine a final route alignment, as well as to identify potential project impacts, costs, and mitigation measures. Learn how TTC-35 has progressed so far, where we are in the environmental process, and what the next steps will be.

Primary Facilities
Some TTC-35 facilities could be constructed upon completion of the Tier Two environmental studies and in response to a demonstrated transportation need. These facilities would serve as main TTC-35 arteries, with potential connecting facilities playing a supporting role in traffic movement and access. Specific alignments will not be determined until Tier Two studies are complete; furthermore, these facilities have not yet been identified. Please view the Environmental Studies and Maps page for additional information on the two-tiered TTC-35 environmental process.

Corridor Segment Committees
Later this year, four Corridor Segment Advisory Committees will be formed to specifically provide input and advice to TxDOT regarding specific routes or components of the TTC-35 program that would be needed for a particular corridor segment, and also what improvements are needed for existing transportation facilities. The corridor segment advisory committees will be appointed by local entities.
