I-20 Arlington/Grand Prairie Corridor Study


The TxDOT Fort Worth District is conducting a corridor study of I-20 from US 287 in Tarrant County to east of South Carrier Parkway in Dallas County. In the Dallas/Fort Worth area, I-20 was constructed in the 1970s as a four to eight-lane, divided, controlled access highway. It serves as a freight and hazardous cargo route with a mix of residential, industrial, and commercial land uses along the corridor.

Since its construction, the corridor has experienced extensive growth and development. According to the U.S. Census Bureau, Tarrant County was ranked as the fifth fastest growing county in the United States between 2010 and 2019, and Dallas County ranked eighth. This extensive growth and increase in congestion are the catalysts for the need to evaluate the existing corridor and adjacent transportation network.

Proposed benefits

The I-20 Arlington/Grand Prairie Corridor Study limits are through the cities of Arlington and Grand Prairie in Tarrant and Dallas counties. The study will evaluate connectivity and through traffic movements with the adjacent transportation network: State Highway 360 from Mayfield Road to East Sublett Road and President George Bush Turnpike/SH 161/Lake Ridge Parkway from Mayfield Road to Bardin Road. The proposed improvements would increase capacity and ease congestion, thus improving mobility in this area.

Proposed improvements

The I-20 Arlington/Grand Prairie Corridor Study will evaluate potentially adding capacity to the interstate through additional mainlanes and express lanes. Additional proposed improvements within the study limits include continuous frontage roads with bicycle and pedestrian accommodations; ramping improvements with auxiliary lanes; and reconstruction of interchanges and intersections. The study will also identify potential interim breakout projects.

As the study progresses, public involvement will be a key component of the project. Interested residents, property owners and business owners can provide comments throughout the study and at public meetings planned at key milestones during the project.

Get involved

The public will be able to gather information, review schematic plans, meet with TxDOT and consultant staff to ask questions and provide comments regarding the proposed design, right of way, and environmental effects during upcoming meetings. The following is a tentative schedule:

  • Public Meeting 1: Early 2024
  • Public Meeting 2: Early 2025
  • Public Hearing: Late 2025
