I-35 Section in San Antonio to Experience Single Lane Restrictions This Weekend

San Antonio, TX, September 18, 2026 —

Motorists traveling through San Antonio this weekend should anticipate significant traffic disruptions as a section of Interstate 35 (I-35) is set to be restricted to a single open lane. The closures are scheduled to begin this weekend, impacting travel along a specific portion of the busy interstate highway.

The exact location and timing of the lane closures were not detailed in the provided information, nor was the specific reason for the work necessitating such a significant restriction. However, single-lane closures on major thoroughfares like I-35 typically indicate substantial construction, maintenance, or repair activities. Such operations often require extensive lane closures to ensure the safety of work crews and the public, as well as to allow for the efficient completion of tasks.

During periods of reduced lane availability, drivers can expect delays, increased congestion, and longer commute times. Authorities generally advise drivers to seek alternate routes if possible, allow for extra travel time, and exercise caution when navigating through work zones. The impact of these restrictions will likely be most pronounced during peak travel hours, even on a weekend, as residents and visitors utilize the interstate for commuting, errands, and recreational activities.

Further details regarding the specific segment of I-35 affected, the precise start and end times of the closures, and the nature of the work being performed were not immediately available. Commuters are encouraged to monitor local traffic advisories and news updates for the most current information as the weekend approaches. The restriction is expected to conclude after the weekend period, with full lane access anticipated to be restored thereafter, though specific details on restoration timing are pending.
