The Texas Department of Transportation (TxDOT) of Austin will be making improvements to 28 miles of Interstate 35 from SH 45 North to SH 45 southeast though an on-going project known as the I-35 Capital Express Program. It is made up of three stand-alone projects – North, Central and South. The Central project is on a later time frame, while the North and South projects are generally ahead, and on the same timeline.
The North I-35 project’s improvements include, but are not limited to, adding one non-tolled high-occupancy vehicle managed lane in each direction (from SH 45 North to US 290 East), reconstructing bridges, and adding a diverging diamond interchange. TxDOT says that the project will require an additional 17 acres of new right-of-way (ROW), and will displace 5 commercial properties. Offer letters are currently underway and construction is expected to begin sometime this year. Similarly, the South I-35 project’s improvements include, but are not limited to, adding two non-tolled high occupancy vehicle managed lanes in each direction (from SH 71/Ben White Boulevard to SH 45 Southeast), reconstructing bridges, and adding pedestrian and bicycle paths. For the South project, TxDOT says an additional 13 acres of new ROW will be required. Final designs are out, and offers letter are currently being sent to affected landowners. Construction is anticipated to begin in 2022.
