The project would widen US 380 to add capacity and provide safety enhancements with overpasses and a raised median to address current mobility issues, the presentation stated.
TxDOT is studying five conceptual alignments for the project. The study area includes the area north of US 380; it includes the cities of Denton, Providence Village, Frisco, Little Elm, Aubrey, Krugerville, and Celina and the towns of Prosper and Cross Roads.
Option 1 was presented in blue and is the only option to follow the existing US 380 alignment.
Option 2 was presented in yellow and would require new construction. This alignment would leave the existing US 380 alignment to travel northwest along Frontier Parkway and then west to intersect with FM 428. The alignment follows FM 428 to SL 288 and then continues along SL 288 to I-35. This alignment would provide a new roadway crossing at the Ray Roberts Lake greenbelt.
Option 3 was presented in purple and would utilize the Dallas North Tollway traveling north to Frontier Parkway. It would then travel west to intersect with FM 428 to eventually come to I-35. This option would involve toll charges for use of the Dallas North Tollway.
Option 4 was presented in orange and would also use the Dallas North Tollway to connect to FM 428. At 428, this route would travel southwest to US 377, then travel along the existing US 380 to SL 288. The alignment then continues along SL 288 to I-35. This option would also involve toll charges for use of the Dallas North Tollway.
Option 5 was presented in teal and would allow drivers to depart US 380 at the interchange and use the Dallas North Tollway to avoid US 380. Drivers would travel on the tollway to FM 428 and then go west along the future Outer Loop extension. This alignment uses FM 428 to travel south to connect to Loop 288 and then follows Loop 288 to I-35. This is another option that would involve toll charges for use of the Dallas North Tollway.
TxDOT is now considering public input on these proposed alignments. A single recommended alignment will emerge from these studies and public input and will be presented at a public meeting tentatively scheduled to be held in the fall or winter of 2021.
Citizens may submit comments online at www.keepitmovingdallas.com/us380dentonpm2 until Dec. 17. The presentation and more information about the proposed alignments can also be found at this site.
