New Northwest Side flyover ramp opens Saturday at Loop 1604 and I-10

SAN ANTONIO – The Texas Department of Transportation continues adding new flyover ramps at the intersection of Interstate 10 and Loop 1604 as part of a broader north San Antonio highway expansion project.

The fourth flyover ramp is set to open Saturday, which will connect eastbound Loop 1604 to eastbound I-10.

Drivers will be able to access the ramp entry point on Loop 1604, just past La Cantera Parkway, and connect to I-10 before the De Zavala Road exit.

The second flyover opened in early June 2025, connecting westbound I-10 to westbound Loop 1604.
