Hildebrand Closes October 26, and Through December the Detour Runs Through Olmos Park

The electronic message boards are up. San Antonio Water System crews have placed them in four spots: near U.S. 281, at Stadium Drive and Devine Road, at Devine Road and Old Hildebrand Avenue, and at San Pedro Avenue and W. Hildebrand Avenue. Lane closures start in late October while crews locate underground utilities. SAWS expects construction to begin on October 26, 2026. From then on, "portions of Hildebrand will be completely closed 24 hours a day, 7 days a week."

For Olmos Park, the first closure is the segment at the neighborhood's southern edge, and the official detour sends through traffic north onto Olmos Drive. Until the calendar turns to 2027, Olmos Park is the detour.

Why the First Phase Is the One That Lands Here

The project is SAWS job 23-4005, the E. Hildebrand Water Main Replacement. It replaces 4,600 feet of water main along Hildebrand and Old Hildebrand, from McCullough Avenue east to Devine Road. The San Antonio Express-News reports that the mains being replaced are more than a century old, with what SAWS called "a history and high probability of failures." The $11.3 million budget also covers work on Camden Street and Euclid Avenue, which is scheduled for 2027.

The work runs in two segments, and the order matters to anyone who lives near McCullough.

The Express-News places Devine Road about a quarter mile west of U.S. 281. That makes Phase 2 the 281 end of the project. Phase 1 is the McCullough end, and it starts at the intersection where Olmos Park's commercial strip meets Hildebrand. The paper put it plainly: "Detours will take drivers into the Monte Vista and Olmos Park neighborhoods as they travel between San Pedro Avenue and U.S. 281."

Phase 1 also runs through the busiest stretch of the year. Thanksgiving errands, holiday shopping and December dinners all fall inside it.

The Loop Drivers Will Be Sent On

Here is how the published Phase 1 route works for someone heading east on Hildebrand from San Pedro toward 281:

1. Hildebrand stays usable as far as McCullough, where the closure begins.
2. Drivers go around the closed block on a north or south leg. The north leg uses Olmos Drive through Olmos Park. The south leg uses Huisache Avenue through Monte Vista.
3. Shook Avenue is the eastern side of the loop, where drivers rejoin Hildebrand past the closure. San Pedro is the western side.

SAWS's September public-meeting presentation says "Street closures will occur in segments as construction progresses." It labels the surrounding roads on a scope map but does not say how driveways, business entrances, or the cross streets at Shook, Olmos Drive and McCullough will be handled. The deck gives no daily work hours either. SAWS says the map at the top of its project page shows "when and where full road closures will occur." That live map is the reference to check before a morning drive, since it is the document SAWS says it will keep updated.

East Olmos Drive is one of the roads now taking detour traffic, and it already changed this year. The City of Olmos Park's February 13, 2026 newsletter said the East Olmos Drive and Devine Drive intersection had been running as an all-way stop since a storm damaged its signal. A city study found a permanent all-way stop to be safe. The city planned stop signs, refreshed pavement markings and a flashing-red beacon, with work set to start in March and mostly finish in April. If your Olmos Drive routine dates from before this spring, expect that corner to look different from what you remember.

The Errands That Sit Inside the Loop

The Phase 1 closure surrounds a cluster of everyday stops, all on Hildebrand itself or on the streets carrying the rerouted traffic.

• Dough Baby, 4219 McCullough Avenue. The longtime Pearl Farmers Market vendor opened its first storefront in July 2026 and is open Wednesday through Sunday. It is closed Monday and Tuesday. Axios San Antonio described it as a grab-and-go bakery known for kolaches and cinnamon rolls, with seasonal pies, quiche, coffee and tea. It also keeps its weekend stand at the Pearl. We wrote about what its arrival meant for mornings on this corridor in The Bakery That Finally Fixed McCullough Avenue's Morning Problem.
• Olmos Pluma, 5223 McCullough Avenue. The coffee shop farther north on McCullough lists daily hours and online ordering on its own site.
• The Tiny Finch, 201 E. Olmos Drive. The Pearl lifestyle boutique's second location sits right on the north leg of the detour. What Now San Antonio reported in July that owner Karen Lee Zachry was targeting an October opening, in a space nearly twice the size of the Pearl flagship. Zachry told the outlet the move was a chance "to meet our neighborhood and our local clientele more where they live and shop and work." As of mid-October, the store's contact page still lists the Olmos Park shop as "Coming Fall 2026." That means it may open in the same weeks Olmos Drive picks up the rerouted traffic.
• STAAMP Allergy, 341 E Hildebrand Avenue. This clinic's address is on Hildebrand itself. Its posted hours are 8 a.m. to 5 p.m. Monday, Tuesday and Thursday, 10 a.m. to 7 p.m. Wednesday, and 8 a.m. to 1 p.m. Friday. The clinic has not published closure-period access details, so patients may want to confirm the approach when booking.

The Hildebrand and McCullough corner was a neighborhood landmark long before any of these shops arrived. The San Antonio Report documented the permanent closure of the Olmos Pharmacy and its soda fountain at that corner in September 2017. The crossroads is the same, and for three months most eastbound traffic will have to turn there.

What SAWS Has Said About Water at the Tap

Road closures are the visible part. The utility work is what can reach individual addresses. SAWS says: "At times, we may need to temporarily shut off water service to connect new lines to the existing system. If your service will be affected, we'll notify you in advance." The meeting presentation adds that "Contractor will coordinate with affected customers directly." It does not say how much notice customers will get or how it will arrive.

SAWS lists Cecilia Picazo as the project contact, at 210-233-3750 or [email protected]. In a September 21 update, the utility reported holding a District 1 meeting for residents and businesses, which Councilwoman Dr. Sukh Kaur attended. The presentation from that meeting is posted on the SAWS project page.

The end date is not quite settled. The SAWS project page gives an approximate timeframe of October 2026 to March 2027, and the Express-News reports the full road reopening in March. The September presentation lists "April 2027" for completion of the Hildebrand site. It is safer to plan around March and allow for April.

One more thing to keep separate. The City of San Antonio's September 4 closure of Hildebrand from just east of San Pedro to just west of McCullough was a one-day repaving job. It was not part of the SAWS project. Anyone who sat through that day and assumed the water main work had already come and gone should know it hasn't.

January Moves the Work Toward 281

On the published schedule, the McCullough-to-Shook block reopens when Phase 1 wraps in December. In January the closure shifts to Shook through Devine Road, the stretch nearest U.S. 281. The published reporting does not yet name Phase 2 detours. Neighbors near the McCullough end should get their corner back first, while drivers heading for 281 face the second round. SAWS has said it will keep posting traffic maps to the project page as the work moves east.

If you plan to list or tour homes near McCullough and Hildebrand this winter, the closure calendar should be part of the plan. Buyers will meet the barricades on their way to a showing. Ignite International Group can help you schedule photography, showings and open houses around the SAWS phases so buyers find your street at its best.
