I-35 Capital Express North Project Groundbreaking by TxDOT.

The Texas Department of Transportation (TxDOT) has begun construction on the Capital Express North I-35 project in Austin, which will cost $606 million and aims to create one high-occupancy vehicle (HOV) managed lane in both directions. The project will also rebuild six bridges, add a diverging diamond interchange (DDI) located at Wells Branch Parkway, reconstruct all entrance and exit ramps, and add intersection bypass lanes. The project is part of a $5 billion plan to decongest I-35, which includes the controversial Capital Express Central project.
