Study Overview

TxDOT is committed to improving mobility and increasing safety for motorists using the US 57 corridor from the US-Mexico border crossing in Eagle Pass to I-35 south of San Antonio. The TxDOT Laredo and San Antonio Districts are responsible for the US 57 corridor, which travels through Maverick, Zavala, and Frio counties and has three international border crossings: one for passenger vehicles, one for commercial vehicles, and one for rail.

Study Purpose

The purpose of the study is to evaluate the feasibility of converting US 57 to an interstate highway, as well as how to improve east/west connectivity, enhance safety, align with previous local and state planning efforts, and promote community development and economic opportunity at the border and along the corridor.

Study Approach

The approach to conduct the US 57 Study is to:

  • Define the purpose and need for improving US 57
  • Evaluate interstate feasibility
  • Perform traffic, safety, and economic analyses for existing and future conditions related to congestion, safety, freight mobility, and cost-benefit
  • Develop and screen short, medium, and long-term transportation solutions
  • Formulate a phased and prioritized improvement program along US 57 using project prioritization metrics
  • Conduct and incorporate stakeholder and public input

Stakholder & Public Engagement

Area stakeholders, cities, and counties along the corridor will have several opportunities to provide input and comment on proposed improvements. The study team is currently conducting two focus group meetings:

  • East – East of La Pryor to the corridor’s intersection with I-35
  • West – West of La Pryor to the border crossing in Eagle Pass and into Coahuila, Mexico

Anyone is welcome to share input at this stage by taking the focus group survey online. Click on the image below to answer survey questions and provide your feedback.

Online Engagement Tool Share Your Feedback

TxDOT will seek public input on the study at a virtual public meeting later this year. The virtual public meeting video and other materials will be available online and comments will be accepted in a variety of formats.
