Lane Closures on Loop 410 and I-35 Highlight Friday Commute

Morning Outlook and Road Conditions

Commuters in San Antonio should prepare for a mix of construction-related delays and residual impacts from recent winter weather this Friday, January 30, 2026. While major thoroughfares have largely cleared following the early-week arctic blast, transportation officials urge caution on overpasses and secondary roads where localized patches of moisture may still be present during the early morning hours. Traffic volume is expected to be heavy on I-35 and I-10 as the city heads into the weekend.

Major Roadworks and Lane Closures

Several significant construction projects are impacting travel times today. Drivers should be aware of the following specific closures:

• Loop 410 Frontage Road: Starting at 3:30 PM today, a single right lane closure will be in effect on the eastbound Loop 410 frontage road from Babcock Road to Fredericksburg Road. This closure is necessary for the demolition and reconstruction of sidewalks, driveways, and curbs. Expect slow-moving traffic in the Northwest Side area through the evening rush.
• Interstate 35 Downtown: TxDOT crews are continuing bridge joint work on the northbound main lanes of I-35 between I-10 and I-37 near the Pearl district. Alternating lane closures are expected to remain in place throughout the day. Commuters heading toward downtown should anticipate bottlenecking in this corridor.
• US 90 Expansion: Active construction continues as part of the US 90 expansion project. Motorists should look out for crews performing base repairs and guardrail work. Night work is scheduled for the late hours, but daytime concrete work may result in shoulder closures near the West Side.
• Loop 1604/I-10 Interchange: Preparations for weekend bridge construction on the far Northwest Side are underway. While main lanes are currently open, expect increased activity and potential short-term ramp disruptions as crews move equipment for the ongoing expansion project.

VIA Metropolitan Transit Alerts

VIA Metropolitan Transit has issued several detour notices for Friday due to both ongoing construction and the lingering effects of recent weather conditions. Riders should check their specific routes before heading to their stops. Notable updates include:

• Route 34 (South St. Mary’s Frequent): Currently on detour due to construction. Service is impacted between Goliad & Lasses and SE Military Drive.
• Route 36 (South Presa): Multiple detours are active near the Brooks Transit Center and along New Braunfels Avenue due to infrastructure work.
• Routes 5 and 22: These routes continue to see temporary adjustments in the downtown and east-side areas due to city-wide maintenance projects.
• Route 524 and 619: Minor weather-related detours remain in place for portions of these routes on the South Side, particularly near General McMullen and General Hudnell Drive.
