The Road That Will Redraw Flower Mound Is Moving Toward a Decision

If you live on the north or west side of Flower Mound and you've been half-following the Denton County Outer Loop project, now is the time to pay full attention. The county has been working toward a preferred alignment announcement — the moment when one route out of four goes from "option" to "plan" — and a public hearing was scheduled for spring 2026 to mark exactly that gate.

Here's what the project actually is. Denton County, in partnership with TxDOT, is developing an Environmental Impact Statement to construct a six-lane freeway primarily on new location connecting I-35 in Denton County with the Dallas North Tollway in Collin County. The project spans approximately 23 miles. It would run through the Greenbelt Corridor between Lake Lewisville and Lake Ray Roberts. That greenbelt sits directly north of Flower Mound. Which route gets chosen matters enormously to anyone on this side of town.

In this EIS, Denton County and TxDOT are evaluating four alternatives for a new location six-lane freeway in addition to a "no-build" alternative. Plans on the Outer Loop website show one option with a plan to start the freeway at Milam Road and another that starts further north at Rector Road. Those starting points translate into very different impacts for neighborhoods just north of town. No decisions have been made about a final alignment — but the window for input is closing.

Denton County spokesperson Dawn Cobb said the county expects to announce the preferred alignment of the project ahead of another public hearing in late spring 2026. That hearing is either imminent or just behind us. Check DentonCountyOuterLoop.com for the current status — the county posts all meeting materials, exhibit boards, and an interactive comment map there.

Why does any of this touch your week? Three reasons the county itself named: rapid population and traffic growth, high crash rates on nearby roadways, and limited mobility in the area due to a lack of east-west routes. Every one of those is a lived reality for anyone who's tried to get from western Flower Mound to I-35E on a weekday morning.

The long horizon is genuinely long. A timeline on the project website estimates the final buildout of all six lanes will be completed around 2050 — but a two-lane frontage road could be completed as early as 2035, and a second two-lane frontage road could be done around 2040. A decade feels abstract until you realize the route being chosen right now determines which roads become cut-throughs, where ramps land, and which parcels near interchanges become commercially valuable overnight.

Transportation projects require years of advanced planning and development, which is why the county must plan now for the growth it expects in the next 30 years. With a population of 1.07 million people in 2025, Denton County is projected to grow to 1.88 million people by 2050. Those people will need roads. The question is where those roads go.

One honest caveat: the county is still in the environmental review phase, and no construction funding is locked. This could still slow down. But the route — once the preferred alignment is named — becomes extremely hard to move. The design schematics are public. The interactive map is live at DentonCountyOuterLoop.com. If you want your street, your neighborhood, or your commute to be part of the record, that's the place to go.
