The Texas Department of Transportation (TxDOT) is widening Collin County’s Farm-to-Market Road 455 in a proposed expansion from Dallas Parkway to Shady Brook Lane. Because the population in Celina, TX has increased by over 26.6% since the year 2000, TxDOT seeks to relieve traffic congestion and inefficient roadways.
The recommended alternative route for the existing FM 455 is 9.2 miles in length and estimated to cost $129 million. TxDOT seeks to acquire 65 acres, including a total of 81 parcels with 6 residential displacements as the potential result of this project. The new roadway expansion will be split into two phases: an interim 4-lane roadway as the first installation, and the construction of the 6-lane roadway will conclude the project. The proposed ROW will vary between 120 ft – 150 ft. TxDOT will construct turn lanes at intersections and side streets. The new lanes will be between 11 and 12 feet.
TxDOT states that it opted for a proposed alternative FM 455 route because expanding the existing ROW does not offer flexible expansion prospects and would condemn a larger volume of properties than that of the new route. TxDOT completed its feasibility study in summer 2024. TxDOT’s next steps are determined by the schematic and environmental project phase, where TxDOT will likely also determine the new ROW.
