East Hildebrand Avenue Faces Extended Road Closure

A significant water main replacement by the San Antonio Water System (SAWS) has forced the closure of a major section of East Hildebrand Avenue, starting Monday, October 26, 2026. This road closure in San Antonio is necessary to upgrade and replace aging water mains, with completion projected for March 2027.

Project Overview and Timeline

According to announcements from San Antonio Public Works and Capital Delivery, the closure will impact drivers who regularly use Hildebrand between McCullough Avenue and Devine Road. The public is advised to plan for traffic detours and use alternate routes while the work progresses over the coming months. Preliminary work on the project began October 21, 2026.

Scope of the Water Main Replacement

The SAWS Hildebrand Avenue water main project will see approximately 4,600 feet of water mains replaced to ensure reliable future service. These mains have experienced frequent breaks, prompting the need for a substantial infrastructure upgrade and pipeline replacement. This section is part of the broader 2023 Water Main Replacement Project 4, which encompasses three construction sites in total.

Expected Disruptions and Detours

The affected area will undergo a 24/7 phased full road closure, impacting local residents and commuters. SAWS states they will implement traffic control measures to minimize disturbances, though detours and lane closures are expected within construction zones. A map of these detours has been shared on social media to assist drivers navigating the impacted section of Hildebrand Avenue.

Impact on Water Service and Customer Notifications

During the course of the water main repair, SAWS may occasionally need to temporarily shut off water service to connect new lines to the existing system. Customers who will be affected by any water service interruption will receive advance notification from SAWS. The primary goal is to replace aging infrastructure and enhance the reliability of water delivery to local customers.

Project Cost and Timeline

The total cost of the Hildebrand Avenue water main replacement is estimated at $11.3 million. The project is scheduled for completion by March 2027, with ongoing updates expected from SAWS and city public works through their respective channels.
