With the highway below ground and access points placed in the cap, our street grid can be stitched back together, providing better traffic dispersion and more connections for biking and walking.

A full cap of the sunken highway is vital to shifting the frontage roads in and placing them on the cap. The shift would free 30 acres of new land for affordable housing.

The new boulevard would be a quality public space; safer and more comfortable for all users with more open spaces, trees and landscaping.

I-35’s current location is the ideal corridor for high-capacity transit. Stations downtown would connect the underground interstate and the street above with buses and light rail.

Address Pollution

The worst air quality in Austin tracks I-35. A new tunnel ventilation system would scrub pollutants from the air, and new trees above ground would help mitigate CO₂ emissions, improve water filtration, and reduce heat islands.
