The Dallas North Tollway Extension: Phase 4 & 5 (U.S. 380 to Collin/Grayson county line to FM 121)
Initial planning is under way for a proposed extension of the Dallas North Tollway (DNT) from U.S. 380 north to the Collin/Grayson county line (Phase 4) and north from Collin/Grayson county to Farm-to-Market (FM) 121 (Phase 5). The length of this extension is approximately 17.6 miles. A scope of work is currently under development, which includes corridor analysis, initial toll feasibility and environmental analysis.
Currently, efforts are under way with Collin County to provide a two-lane county road in the proposed tollway extension corridor from U.S. 380 to FM 428 near Celina. This includes constructing a transition section by August of 2007 just north of U.S. 380 to connect with the DNT Extension Phase 3 frontage roads. A groundbreaking ceremony was held on April, 20, 2007 for this road. North of FM 428, work is ongoing to determine the final alignment of the tollway extension.
At the July 2007 board meeting, the NTTA took a major step forward when the Board of Directors approved a work authorization for a corridor manager position for the Phase 4 extension of the Tollway. The corridor manager will ensure all necessary development tasks, from environmental clearances to detailed design development and construction, are identified and executed.
