Overview
The Trans-Texas Corridor (TTC) is a proposed multi-use, statewide network of transportation routes in Texas that will incorporate existing and new highways, railways and utility rights-of-way, as needed. Specific routes for the TTC have not been determined. As envisioned, each route will potentially include: separate lanes for passenger vehicles and large trucks; freight railways; high-speed commuter railways; infrastructure for utilities including water lines, oil and gas pipelines; and transmission lines for electricity, broadband and other telecommunications services.
Plans call for the TTC to be completed in phases over the next 50 years, with routes and modes prioritized according to Texas’ transportation needs. TxDOT will oversee planning, construction, and ongoing maintenance, although private vendors will be responsible for much of the daily operations.
TTC Projects
There are currently two TTC projects under development: I-69/TTC, which extends from Texarkana/Shreveport to Mexico (possibly the Rio Grande Valley or Laredo) and TTC-35, which generally parallels I-35 from north of Dallas/Fort Worth to Mexico and possibly the Gulf Coast.
