SAN ANTONIO – Downtown San Antonio drivers will have to navigate through a new round of construction on Interstate 35 and Interstate 10 through November.
The northbound upper levels of I-35 will have two main lane closures from I-10 near Martin Street to McCullough Ave.
Work on bridge joint repairs will begin on Tuesday and continue through November 2025.
Additional work will continue in this area through spring 2026.
