Correction: this story was updated May 7 to properly reflect the projects that were allotted funding.

The Transportation Policy Board, the governing body of the Capital Area Metropolitan Planning Organization, voted unanimously May 6 to grant the Mobility35 Capital Express Project a total of $500 million in additional funding toward the project to revamp I-35 in Austin and other projects.

“In terms of giving an unequivocal statement to the chairman and the commission, I think it’s important that we do that today,” Mayor Steve Adler said before voting on the resolution, which was recommended by the Texas Department of Transportation Austin District and CAMPO staff.

In total, the project would cost $8.1 billion, with around $5.6 billion funding construction costs.

An additional $400 million of funding from the TPB will be directed toward the construction of new expressways from SH 45 North in Round Rock to SH 45 Southeast. The remaining $100 million will be split intersection improvements at RM 620 and Anderson Mill Road and new Toll 183A frontage roads. The commitment will be financed through Category 2 and 7 funding and is conditional upon Mobility35 receiving the balance of the funding required for the project from Texas Transportation Commission-directed sources.

CAMPO’s agenda materials distributed prior to their May 6 meeting stated the additional financial commitment would “serve as the reaffirmation that IH 35 is the top priority in the CAMPO region.”

Prior to the May 6 vote, the TPB and TxDOT had already collectively committed $805 million to the Mobility35 project.
