Weekend overnight closures set at Loop 1604 and I-10 interchange, affecting frontage roads and La Cantera access

What drivers should expect in Northwest San Antonio this weekend

Several overnight closures are scheduled this weekend around the Loop 1604 and Interstate 10 interchange on San Antonio’s Northwest Side as bridge work continues on the Loop 1604 North Expansion Project. The work is planned to take place nightly from 9 p.m. Friday, February 6, 2026, through 5 a.m. Monday, February 9, 2026, with timing subject to weather and field conditions.

The work zone centers on the interchange area that serves heavy commuter traffic as well as access to major commercial destinations near La Cantera. Traffic control is expected at key intersections, and drivers should anticipate slower travel times and additional wayfinding needs, particularly for late-night trips to and from I-10 and Loop 1604 frontage roads.

Planned closures

The scheduled closures include segments of Loop 1604 frontage roads and ramps in both directions near the interchange, along with restrictions on I-10 frontage road movements at the same location. The work also includes the La Cantera Parkway intersection at I-10, including U-turn movements.

• Eastbound Loop 1604: exit ramp before the I-10 interchange (closure planned overnight).
• Eastbound Loop 1604 frontage road: alternating closures between the pre-interchange exit ramp and the eastbound I-10 frontage road.
• Westbound Loop 1604 frontage road at the interchange: closure planned overnight.
• Westbound I-10 frontage road at the interchange: closure planned overnight.
• La Cantera Parkway at I-10 (including U-turns): intersection restrictions planned overnight.

Detours and local access

Detours are expected to route drivers away from closed ramps and frontage road segments while maintaining access through nearby exits and surface-street connections. For example, eastbound Loop 1604 drivers attempting to reach the eastbound frontage road before the interchange are expected to use the Chase Hill Boulevard exit and continue along the eastbound Loop 1604 frontage road through the La Cantera Parkway area.

Closures may open earlier than scheduled if work is completed ahead of time, and traffic patterns may change during the work window based on construction needs.

Project context

The weekend restrictions are part of the broader Loop 1604 North Expansion effort, a long-term reconstruction and widening initiative across the North Side that includes major interchange rebuilding at I-10. While multiple flyover connections are already in service, bridge construction and related work continues around the interchange footprint, requiring periodic overnight and weekend closures to safely set materials, shift traffic patterns, and complete elevated structure work.

Drivers planning travel in the corridor overnight should consider alternate routes, allow additional time, and expect intermittent changes to turning movements near La Cantera Parkway and the I-10 frontage roads.
