Weekend Lane Closures Alert: Heavy Delays Expected on Loop 1604 and I-35 NEX

Commuter Alert: Navigating San Antonio Traffic this Weekend

San Antonio motorists should prepare for significant travel impacts this Saturday, February 28, 2026, as multiple major highway expansion projects reach critical phases. Construction crews are taking advantage of the weekend weather to push toward several spring completion deadlines, particularly on the city's North and Northeast sides. If you are planning to travel across the northern arc of the city, expect heavy congestion and localized detours throughout the day.

Loop 1604 North Expansion Progress

The massive Loop 1604 North Expansion remains the most significant factor for weekend drivers. Segment 3, which stretches from I-10 to US 281, is now approximately 93 percent complete and is entering its final months of construction. Motorists should anticipate intermittent lane closures as crews finalize paving and ramp transitions near the US 281 interchange. While travel relief is expected by late spring, today's work will likely cause bottlenecks between Stone Oak Parkway and Blanco Road.

• I-10 Interchange: Five of the eight planned flyovers are currently operational, significantly improving flow for those connecting from eastbound 1604 to I-10. However, work continues on the remaining connectors, with occasional closures of the lower-level cloverleaf ramps.
• Lookout Road: Periodic weekend closures of the main lanes on Loop 1604 from Pat Booker Road to Lookout Road are ongoing to facilitate bridge deck work. Traffic should follow posted detour signs through the intersection.

I-35 Northeast Expansion (NEX) and US 90

Construction for the I-35 NEX project continues to impact the Northeast Side. The project, which covers 20 miles from North Walters Street to FM 1103, involves the construction of elevated lanes that are now visible across the corridor. Drivers through Schertz and Live Oak should watch for narrow lanes and reduced speed limits as work continues on the central segment through late 2027.

• I-35 Central: Elevated structure work is concentrated between I-410 and the Bexar County line. Watch for shifting lane patterns in this high-traffic zone.
• US 90 West: The expansion project between I-410 and SH 211 remains active in Far West Bexar County, with crews focusing on bridge structures and road widening to accommodate the area's growth.

Public Transit and Local Updates

For those utilizing VIA Metropolitan Transit, standard fares remain in effect. On February 24, the VIA Board of Trustees officially rejected a proposal for a fare-free pilot program, citing the need to protect federal funding for the upcoming Green and Silver rapid transit lines currently under construction. Transit users should check their specific routes for minor weekend timing adjustments as the agency prepares for a larger service update scheduled for May.

Drivers in the downtown area may experience improved movement near the Zona Cultural as several long-term street improvement projects on San Saba Street have recently concluded. However, localized lane restrictions persist near the Alamo as preservation work begins on the historic church foundation this spring.
