Study Overview

TxDOT works to deliver a safe, reliable and integrated transportation system. The I-20 Texas Corridor Study, conducted by TxDOT’s Department of Transportation Planning and Programming Division, will identify multimodal needs and prioritize improvements that facilitate the movement of people and goods from east to west Texas. The study area spans along I-20 from the I-10 junction in Reeves County to the Texas/Louisiana state line, a distance of 635 miles. I-20 is one of the primary east-west travel routes in Texas. The corridor is used for travel, trade and as a primary evacuation route from I-635 to the Texas/Louisiana state border in case of an emergency.  

I-20 Corridor Map

The I-20 Corridor Study is critical to maintaining both a regional and national transportation system that is safe, efficient and responsive to future growth.

Key Considerations

Potential improvements to the I-20 corridor will be identified in collaboration with the stakeholders and public by analyzing multiple elements, such as:

  • Safety conditions
  • Existing infrastructure conditions
  • Congestion and capacity needs
  • Alternative routes and corridor resiliency
  • Multimodal passenger and freight options
  • Truck parking locations
  • Traffic operations and Intelligent Transportation Systems
  • Frontage road connectivity and continuity
  • Funding mechanisms and financing strategies
  • Compatibility with adjacent uses and future growth trends

Study Approach

TxDOT will work with local government officials, organizations, community members and experts to identify potential future improvements, perform analyses, collect data and create a corridor development strategy. The diagram shows the general proposed approach.

Stakeholder & Public Engagement

Public and private sector input will be a critical component of the I-20 Corridor Study. The public will be engaged through a Corridor Steering Committee and three Segment Working Groups:

  • West – I-10 to Dallas-Fort Worth (DFW) Metroplex
  • Central – DFW Metroplex
  • East – DFW Metroplex to Texas/Louisiana State Line

The public will also have opportunities to provide input throughout the development of the study.
