The Texas Department of Transportation is staying transparent on all major projects as Denton County roads continue to get makeovers.

For the second time in less than a month, TxDOT held an informal meet-and-greet at Gene Pike Middle School in Justin to allow the public a chance to ask engineer questions and view construction blueprints. This month's spotlight is a major overhaul of FM 1171, which runs through Lewisville, Flower Mound, Argyle, Northlake and Justin.

TxDOT held a similar public gathering in March to discuss the widening of FM 407, another major Denton County artery that will have a facelift come 2028.

The details: In the interim, FM 1171 would be expanded to four 12-foot-wide lanes and a depressed median in rural areas. Eventually, the road would become a six-lane, 12-foot-wide road.
  • There will be 3.5 miles of construction involving the cities of Justin and Northlake.
  • All construction would be done west of I-35W.
  • In urban areas, the road would be expanded to six 12-foot-wide lanes with a depressed median.
The “urban area roads” would connect to the existing FM 1171 road and continue west, stopping shortly after the Qual Creek Shooting Range in Northlake.

Estimated cost: Officials peg this project at around $118 million.


Shared space: TxDOT placed an emphasis on shared pedestrian space for this project. As such, all urban sections of roadway will include a pedestrian and bicycle shared-use path and sidewalk, according to officials.

Dates to know: TxDOT released a tentative schedule of need-to-know dates for the public in regards to FM 1171's expansion.
  • Summer 2023: environmental clearance by TxDOT
  • Summer 2023: right of way acquisition begins; public will see beginnings of construction
Anticipated ready-to-let date: Construction crews will begin bidding on this project in 2026, per officials.
