What is the I-635 project, and how long will it take?

TxDOT is reconstructing an 11-mile segment of I-635, from U.S. 75 to I-30. The goal is to improve both safety and mobility across this stretch, all the way from North Dallas to Mesquite. The project costs $1.74 billion and started in spring 2020, according to TxDOT.

The reconstruction will provide five main lanes and two managed lanes in both directions, continual frontage roads starting at Town East Boulevard and full reconstruction of the I-30/I-635 interchange.

The project is expected to be completed by 2024.
