Council adopts Monarch thoroughfare amendment, reserves right‑of‑way for future Argyle bridge
Loading...
Summary
Council approved a thoroughfare map amendment in the town's northwest sector that removes a proposed east–west collector and reserves right‑of‑way to allow a future Argyle bridge connection if built; traffic modeling drove the change to an undivided four‑lane classification in places.
The Town Council approved the Monarch Thoroughfare Plan Amendment (MPA 25‑0003), a map change affecting the far northwest portion of Flower Mound.
Planning staff presented the amendment after previous handling by the Transportation Commission and Planning & Zoning. The proposal replaces a planned urban collector in places with an Urban Minor Arterial Undivided cross section and removes a separate east–west collector through the development area. Staff emphasized that a prior traffic impact analysis showed the four‑lane classification was necessary to meet long‑term capacity projections; the town also included a reservation of right‑of‑way that would allow a future bridge connection to the neighboring city of Argyle if Argyle elects to build it. Council accepted the change and advanced the updated thoroughfare map.
Council noted the change does not commit Flower Mound to pay for a potential Argyle bridge; the amendment only reserves corridor space. Staff said intersection improvements at FM 1171 and Shiloh — already on the CIP — will help manage traffic as the area develops, and they recommended ongoing monitoring of key intersections.
Quote: “By removing the urban collector and switching Shiloh to the urban minor arterial undivided, we avoid capacity assumptions that the traffic study had to make,” the town’s transportation planner said.
Ending: The amendment passed unanimously. Engineering staff will factor the map change into future site plan reviews and CIP coordination.
