East Hildebrand Avenue Is Closed Between McCullough and Devine for a Water-Main Replacement Running Through March 2027
The San Antonio Water System's $11.3 million project replaces 4,600 feet of aging mains at three sites — a standing detour on the near-North Side that PM-drive and Election Day drivers should route around.

A stretch of East Hildebrand Avenue between McCullough Avenue and Devine Road is closed while the San Antonio Water System replaces aging water mains, in reporting on the project read by the desk this cycle. The work is the 2023 Water Main Replacement Project 4: 4,600 feet of pipe across three separate construction sites, a total investment of $11.3 million, with completion slated for March 2027. Preliminary work began October 21 and the Hildebrand section closed October 26.
For drivers, the closure is a standing one, not a nightly one: the section stays closed through the project, with detours between the McCullough and Devine segments, and operators in the area may face temporary water service interruptions as crews connect new lines to the existing system. The reporting advised businesses along the corridor to prepare for construction-related detours until the project concludes and to coordinate delivery and vendor routes around the closed segment.
The desk carries the closure into the Monday PM drive and Tuesday's Election Day voting traffic as the near-North Side's standing detour, alongside the day's already-published items: the Loop 410 Honeysuckle Lane and Blanco Road ramp closures on the North Side and tonight's 9 p.m. Frost Bank Center Drive right-turn lane closure off the northbound I-35 frontage road. Drivers crossing the Hildebrand corridor should use the signed detour and allow extra time.
