Theresa De La Rosa's Broker Perspective
I'm Theresa De La Rosa, Broker of Covenant Heritage Realty in Northlake. Long Prairie Road and Flower Mound Road are the intersections Flower Mound residents drive every day, whether they are heading to the shops on Long Prairie, to Grapevine, or to the freeways south of town. When I work with buyers in Flower Mound, I ask them to test their commute as it works today, during construction, and then consider what the finished intersection adds. A project like this is a near-term inconvenience with a long-term capacity gain, and the schedule is the part to verify, not assume.
What Is Being Built at FM 2499 and FM 3040
The project is a Town of Flower Mound intersection improvement at the crossing of FM 2499 (Long Prairie Road) and FM 3040 (Flower Mound Road). According to the Town's project documents and reporting from Community Impact and the Cross Timbers Gazette, the intersection is being reconfigured to add:
- A dual left-turn lane in each direction, replacing the current single left-turn configuration.
- Three through lanes in each direction through the intersection.
- A dedicated right-turn lane in each direction, while maintaining the existing dual right-turn lanes for eastbound traffic.
- New traffic signals and ADA-compliant pedestrian ramps.
The work is intended to increase the intersection's capacity and reduce the queueing that builds at peak hours on one of Flower Mound's busiest crossings. A portion of FM 2499 south of the town center was renamed International Parkway in 2019, so drivers may see either name on signage depending on the stretch.
Funding and Schedule
The Flower Mound Town Council awarded the construction contract to 2L Construction in March 2026 under solicitation RFB No. 2025-101-B. The construction contract is about $2.82 million, with the project total cited at roughly $3.5 million including Denton County funding through an interlocal agreement approved in September 2025.
Construction began at the intersection on Monday, July 6, 2026, and the project is expected to be completed by July 2027. As of mid-October 2026, work is active at the intersection. The Town of Flower Mound posts current project and closure information on its official site, and that is the place to verify lane closures and signal changes before relying on a specific route.
Why This Intersection Matters to Flower Mound
FM 2499 (Long Prairie Road) is a primary north-south arterial through Flower Mound, connecting the town to Grapevine and the DFW Airport area to the south and to Highland Village and points north. FM 3040 (Flower Mound Road) connects the same area toward Grapevine to the southwest. The crossing is a gateway for residents heading to work, to the airport, and to the retail and services concentrated along Long Prairie Road.
For households comparing Flower Mound vs. Argyle for two commuters, this project is one of several road improvements shaping commute times in the area. It joins the completed FM 407 Micro Breakout at I-35W and the planned I-35W frontage road work as pieces of the region's transportation picture. None of them should be read as a guarantee of future values; they are capacity and access changes that affect daily convenience.
What It Means for Buyers and Sellers
For buyers, the practical question is the same as for any active road project: test the commute at your real travel times during the construction window, and verify the current phase with the Town before relying on a route. The finished intersection, with dual left turns, three through lanes and dedicated right turns, is designed to move more traffic through the crossing, but the benefit arrives only when the work is complete.
For sellers near the intersection, be ready to answer questions about the project's status and timeline accurately. A listing positioned with current, honest commute information serves buyers better than a claim about future road improvements. The Flower Mound relocation guide covers the town's neighborhoods, schools and commute context in more depth.
