What is the I-30 Project?

The I-30 Project is a TxDOT study to develop long-term transportation and operational improvements on Interstate 30 (I-30) generally east of downtown Dallas, across eastern Dallas County. The purpose of the Project is to improve safety, address congestion, improve traffic operations, and address roadway deficiencies.

As shown on the map below, the Project will study 17 miles of the Interstate, from just east of the new I-35E/I-30 “Horseshoe” interchange near downtown Dallas, to Bass Pro Drive in Garland. The 17-mile segment passes through the cities of Dallas, Mesquite and Garland. The color codes on the map below show study segments:

  • Yellow – the I-30 Canyon alongside Downtown Dallas
  • Red – I-30 (East RL Thornton Freeway) in Dallas
  • Orange – I-30 in Mesquite out to the I-635 Interchange
  • Green – I-30 in Mesquite and Garland from the I-635 Interchange to Bass Pro Drive

The I-30 Project will include a public involvement program focused on corridor communities, to provide an opportunity for the public to become fully informed about the project, and to encourage and solicit input. This website is set up to provide project news and information, which will be posted to the site as these are developed.

Project Concept

Specific proposals for transportation improvements in the I-30 Study Corridor will be subject to the public involvement processes described on this website, as well as engineering and environmental studies by TxDOT. The following segment descriptions are provided to give an approximate scope of intended work. These descriptions are conceptual and subject to change.  The descriptions should be expected to be updated as the I-30 Project progresses.

I-30 Canyon: From I-35E to I-45 (Yellow on Map)

In addition to the descriptions above, TxDOT has conducted a planning study called CityMAP which is generally focused on the freeway loop surrounding downtown Dallas. The assessments and recommendations from the CityMAP Study for the I-30 corridor will be taken into consideration during the initial public involvement phase for the I-30 Project, and may be carried throughout the design schematic phase of the project.
