San Antonio drivers who count on Loop 1604 for late-night trips are in for a rough week. Starting Monday night, a busy stretch of the westbound frontage road will be shut down nightly so crews can tackle utility work tied to a larger expansion project. The closure runs from the Blanco Road entrance ramp to Huebner Road from 9 p.m. to 5 a.m. on weeknights, with law-enforcement officers stationed at key intersections to manage local access and keep traffic from grinding to a halt, as reported by MySA.
What Closes And When
According to MySA, the nightly shutdown begins at 9 p.m. on Monday and repeats each night through 5 a.m. on Friday. The impacted stretch is the westbound Loop 1604 frontage road between the Blanco Road entrance ramp and Huebner Road, a key North Side connector that regularly carries a steady stream of local traffic even after dark.
Suggested Detours And Workarounds
TxDOT’s detour playbook focuses on shuttling drivers between the frontage road and the main lanes. Drivers heading west on the frontage road are advised to hop onto the main lanes using the entrance ramp just past Blanco Road, then drop back down to the frontage road via the Bitters Road exit ramp once they have cleared the construction zone. Those who specifically need to get to Huebner Road can make a U-turn at Blanco and use the eastbound frontage road to reach Huebner.
Closure notices from TxDOT say off-duty officers will be on site to direct traffic through intersections as needed, a small consolation for anyone stuck navigating cones and flashing arrows in the middle of the night.
Why Crews Need The Overnight Closures
The nightly shutdowns are tied to utility relocations for the broader Loop 1604 North Expansion Project, which aims to widen and rebuild the busy North Side corridor. The long-term work includes a multi-level interchange at I-10 and is part of an effort valued at roughly $1.4 billion to expand the highway and add express lanes, according to the Express-News. In other words, this week’s overnight frustration is one small piece of a very big construction puzzle.
Local Access And What Residents Should Know
Residents of Costa Bella Apartment Homes will still be able to get in and out via Huebner Road, with uniformed officers guiding access through the closure area. Businesses and homes tucked inside the work zone will also retain local access, MySA reports. The schedule is weather dependent, so drivers who typically rely on this portion of the frontage road at night should allow extra time and be ready for last-minute changes.
How To Stay Updated
For the latest on timing, detours and any weather-related postponements, check closure notices from TxDOT and keep an eye on the agency’s San Antonio District social media channels. Local traffic coverage from outlets like KSAT will also flag any early reopenings or extended closures, so night owls and early commuters alike can adjust their routes before they hit the road.
