Flower Mound’s long wait for its own Whataburger is finally almost over. Work is underway on a single-story, 3,335-square-foot restaurant at 3201 Long Prairie Road, with the first burgers expected to be served in late spring. The new spot will include two drive-thru lanes and sit on a freshly built multi-restaurant pad near Sagebrush Drive.
Project filing and timeline
In a project registration filed with the Texas Department of Licensing and Regulation, Whataburger outlines plans for a 3,335-square-foot, single-story building at 3201 Long Prairie Road with an estimated construction cost of about $2.5 million. The state filing lists a March 17, 2025 construction start and a Sept. 8, 2025 completion date. More recent local coverage has shifted expectations to a late-spring opening as part of a larger retail build-out in the area, according to Community Impact.
Town approval and site plan
The Flower Mound Town Council unanimously approved the Whataburger project in April 2023, bundling it with plans for Slim Chickens and Dutch Bros. As reported by the Cross Timbers Gazette, town economic development director Ray Watson said, “The developer is putting in the horizontal infrastructure right now.” The restaurant pad sits just south of Sagebrush Drive, with land behind the eateries reserved for future medical-office development.
What to expect
According to Whataburger, the chain specializes in made-to-order burgers on toasted 5-inch buns using never-frozen beef, along with breakfast items, chicken sandwiches and shakes. In North Texas, the brand has been in growth mode, with recent openings in Frisco in 2024 and Plano in 2025 noted by Community Impact. The Flower Mound location is expected to offer drive-thru service, app ordering and delivery similar to other newer stores. Hours have not yet been published for the Long Prairie Road restaurant, although several nearby Whataburger sites operate 24/7 with full drive-thru service.
Timing and what could shift
Build-out schedules are not always on a straight line. The Cross Timbers Gazette reported that a nearby Bartonville Whataburger opened in August 2024, about 11 months after construction kicked off, a reminder that local openings can lag behind early projections. The TDLR filing reflects earlier target dates for the Flower Mound site, but the schedule has since shifted into 2026, so residents should expect a formal grand-opening announcement before hiring starts. Once the doors open, the restaurant is expected to bring dozens of new jobs and add to daytime traffic in the Long Prairie retail cluster.
What to watch next
Town staff and the developer are expected to release official opening and hiring details as they are finalized, and Whataburger typically announces grand-opening festivities in advance. When the council first signed off on the project, Council Member Jim Engel said it would be “great to actually have a Whataburger in town,” a comment recorded by the Dallas Express. This story will be updated once the opening date and grand-opening plans are announced.
