Major Loop 1604 Ramp Closures and I-10 Nightly Work Impacting San Antonio Commutes

Navigating San Antonio: Major Loop 1604 Closures and Overnight I-10 Work

Commuters in San Antonio should prepare for significant adjustments this Wednesday, February 25, 2026, as the Texas Department of Transportation (TxDOT) continues major progress on multi-billion dollar infrastructure projects. Between long-term ramp closures on the North Side and planned overnight shutdowns on the East Side, both morning and evening travel will require extra planning and patience.

Loop 1604 North Expansion and North Side Impacts

The Loop 1604 North Expansion remains the primary source of disruption for North Side drivers. As part of the $1.4 billion project to widen 23 miles of roadway from four lanes to 10, several key points are seeing active construction today:

• O’Connor Road Ramp Closure: The westbound entrance ramp onto Loop 1604 at O’Connor Road is now closed for a long-term reconstruction project that began earlier this week. This closure is expected to last until early June 2026. Drivers intending to head west from O’Connor must now continue on the frontage road past Bulverde Road before they can merge onto the main lanes.
• I-10 Access Road at The Rim: For those navigating the shopping districts near La Cantera Parkway, the left lane of the westbound I-10 access road between La Cantera Parkway and Rim Drive is currently closed for drainage work. This restriction is slated to remain in place through late spring.
• Nightly Intersection Work: Starting at 9:00 PM tonight, alternating closures will affect the Loop 1604 intersections at Hausman Road, Bulverde Road, and O’Connor Road. These nightly shutdowns facilitate bridge deck construction and sign installations, with lanes scheduled to reopen by 5:00 AM Thursday.

Overnight Full Closure on I-10 East

Late-night and early-morning travelers on the far East Side will face a total stoppage tonight. TxDOT has confirmed a full closure of the I-10 Eastbound main lanes starting at 9:00 PM on Wednesday, February 25. The closure stretches from the FM 1518 exit ramp to the Zuehl entrance ramp and is necessary for barrier placement and resetting. All eastbound traffic will be diverted to the frontage roads during this period, with a scheduled reopening at 5:00 AM tomorrow.

VIA Metropolitan Transit Alerts

Public transport riders should verify their routes as several major bus lines are currently operating under detours due to ongoing roadwork:

• Route 7 (US 281 Stone Oak / Brooks Express): Detours have disrupted service between Navarro Street and the San Antonio International Airport.
• Route 5 (McCullough): Northbound service is currently detoured near North Star Mall, with stops between Rector and the Loop 410 access road temporarily out of service.
• Route 93 (Roadrunner Express): Service is impacted between Crossroads Park & Ride and the Loop 1604 access road at La Cantera.

In addition to these detours, VIA recently announced that a final vote on the May 2026 Service Improvements has been postponed to March. This delay follows community feedback regarding the potential retirement of Route 2, which officials are now reconsidering.

Commuter Recommendations

Given the heavy construction activity, commuters are encouraged to utilize real-time traffic apps for bypasses. If you are traveling tonight, clear the I-10 Eastbound stretch before 9:00 PM to avoid frontage road delays. For those on the Northeast Side, continue to expect congestion near the I-35 NEX project, where lanes are being expanded from eight to 14 to accommodate the region's growth.
