I-35W is a north-south corridor through Fort Worth, Haslet, and Burleson. At its apex in downtown Fort Worth, it carries over 165,000 vehicles per day. A major national trade corridor, the interstate has daily truck volumes averaging 11 percent. Multiple expansion projects are either planned or underway to improve safety and mobility along 26 miles of I-35W in Tarrant County.

TxDOT has environmentally cleared I-35W from I-30 to Eagle Parkway to ultimately widen the corridor up to eight mainlanes plus up to six TEXpress Lanes for future traffic volumes.

Construction began in 2013 on a $1.6 billion interim project to rebuild 10 miles of I-35W from north of I-30 to US 81/287. Part of the North Tarrant Express, this project will double the existing capacity by reconstructing the current infrastructure, adding four toll TEXpress Lanes, auxiliary lanes and some frontage roads. I-35W from north of I-820 to US 81/287 reached substantial completion in December 2016. I-35W from north of I-30 to north of I-820 reached substantial completion in July 2018.  

Construction began in September 2020 on the next phase of I-35W from US 81/287 to Eagle Parkway. The public-private project will rebuild 6.7 miles of I-35W and add four TEXpress Lanes, auxiliary lanes and some frontage roads. Anticipated substantial completion is late 2023.

I-20 to the Johnson County Line (SH 174)

TxDOT is conducting a long-range study to widen I-35W from I-20 to the Johnson County line. This eight-mile project would add two to four mainlanes to improve safety and mobility. The goal is to develop the schematic and achieve environmental clearance by 2023. No construction funding is currently available for this project.

SH 174 to US 67

TxDOT has identified potential planned improvements for I-35W from SH 174 to US 67 as the region is able to identify future funding. Currently under development is a proposed project that would reconstruct the highway to provide extra capacity and improved design to safely and more effectively accommodate rapidly-growing travel demands.

Proposed improvements will include additional mainlanes, entrance/exit ramp adjustments, auxiliary lane and frontage road improvements, and bicycle and pedestrian accommodations. It is currently under schematic design and environmental assessment.
