The lower Level of Southbound I-35 Downtown Will Be Closed From South Alamo To South Laredo Streets

by Tre Serrano

San Antonio drivers, brace yourselves. Starting today, the lower level of southbound I-35—from South Alamo to South Laredo Street—is closed for bridge joint replacements, with the work expected to last through mid-June.

🛑 What’s Closed?

Southbound I-35 Lower Level
Between South Alamo & South Laredo
Closure includes all access ramps and exits in this stretch

⏱️ How Long Will This Last?

TxDOT estimates the repairs will be completed by mid-June 2025, weather permitting.

🚗 Detours & Driver Tips:

Use Upper Level I-35 or detour via Cesar Chavez Blvd
Expect heavier traffic downtown, especially during rush hours
Plan extra travel time if you live or work in the area
Consider alternate routes like I-10 or US-281 to avoid downtown congestion

🏙️ Why It Matters:

Bridge joint replacements are critical to keeping the highway safe and stable—especially on an aging section of I-35 that carries thousands of vehicles daily. While the short-term inconvenience is real, this project helps prevent long-term structural issues and major closures down the line.
