Severe Weather Alert and Major I-10 Lane Closures Impacting Tuesday Commute

Commuter Advisory: Heavy Rain and Severe Storm Risks

San Antonio drivers should prepare for a challenging commute this Tuesday, March 10, 2026. Local forecasts indicate a high probability of rain throughout the day, with a 75% chance of precipitation and potential severe storms moving into the South-Central Texas region by the evening. The Texas Department of Transportation (TxDOT) urges motorists to reduce speeds and increase following distances, as wet pavement and reduced visibility are expected to impact major arteries including I-10, I-35, and Loop 410.

New I-10 East Mainlane Closures Begin at 9:00 AM

Commuters heading east should note a significant new construction phase starting today. TxDOT has scheduled a right mainlane closure on eastbound I-10 between FM 1518 and the Zuehl Road entrance ramp. This closure is set to begin at 9:00 AM today and is expected to remain in place through Friday afternoon to facilitate the removal of existing rip-rap for bridge extensions. Expect significant bottlenecking near the St. Hedwig area as traffic merges into the remaining open lanes.

Major Traffic Pattern Shift: Blanco Road and Loop 1604

On the North Side, the Loop 1604 North Expansion Project has reached a critical milestone this March. Drivers at the intersection of Blanco Road and Loop 1604 must navigate the city’s first permanent Diverging Diamond Interchange (DDI). Traffic on Blanco Road will temporarily shift to the left side of the bridge over the highway. While designed to reduce left-turn accidents and improve flow, the new configuration may cause initial confusion and slower speeds. Watch for updated signage and temporary signals while crossing the bridge.

I-35 Northeast Expansion (NEX) and Central Construction

The I-35 corridor remains a high-congestion zone as work continues on the elevated express lanes between North Walters Street and FM 1103. Commuters should expect daily delays during peak hours, particularly near the I-35 and Loop 1604 interchange, where crews are working on several of the project's tallest support columns. Additionally, residual cleanup from a major incident on I-37 near downtown yesterday may cause minor shoulder-related rubbernecking during the morning rush.

Public Transit and VIA Rapid Green Line Updates

VIA Metropolitan Transit users should be aware of ongoing construction for the VIA Rapid Green Line along San Pedro Avenue. Segments 1 through 8 are currently under active utility work, leading to intermittent lane and sidewalk closures between the San Antonio International Airport and the downtown area. While bus service remains on schedule, minor stop relocations may occur near the Roosevelt Park and Isom Road segments.

• Avoid I-10 East after 9 AM if traveling toward Seguin.
• Use the VIA goLine or real-time transit apps to track Rapid Green Line adjustments.
• Monitor local radar for severe weather updates before the evening rush.
