TxDOT Interstate 35E Phase 2 Expansion

Lone Star Constructors, Fluor's joint venture with Austin Bridge & Road, was selected by the Texas Department of Transportation (TxDOT) to design, construct and maintain Phase 2 of the Interstate 35E (I-35E) project from I-635 in Dallas to the Denton County line in Carrollton, Texas.

Client's Challenge

This project is part of TxDOT's long-term plan to meet current and future travel demands by improving overall mobility, operational efficiency, accessibility, safety and emergency response. When completed, the project will help alleviate traffic congestion to the surrounding communities and improve connectivity in the Dallas metroplex.

Fluor's Solution

The 6.3-mile design-build project includes full reconstruction and expansion of six existing general purpose lanes to eight general purpose lanes, with new auxiliary lanes at entrance and exit ramps and the reconstruction of frontage roads along the corridor. Two existing reversible toll lanes will also be reconstructed.


Lone Star Constructors was granted final notice-to-proceed for the I-35E expansion in March 2022. Completion is anticipated in early 2026.
