Nightly closures at I-35 merger to take place through Jan. 23

The post states there will be significant delays, and drivers are encouraged to seek alternative routes.

The backstory

The construction at the I-35 split is part of a larger project on the I-35 corridor that will reconstruct and widen the four-lane highway to an eight-lane highway and widen the frontage road at this interchange, according to TxDOT.

The purpose of the project is to address congestion and public safety.

Construction of the $583 million started in the spring of 2025 and is expected to be completed by the end of 2029, according to DriveTexas, which is part of TxDOT.
