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.

BACKGROUND
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.

Public involvement for the DNT Extension Phase 4 project began in January 2008 with a public meeting in Prosper. Technical stakeholder meetings on Phase 4A were conducted in January, March, April and June of 2008. The NTTA held a Phase 4A public hearing on July 24, 2008 in Prosper. After the public comment period, the NTTA System Projects and Operations Committee approved the schematic and environmental assessment. On September 17, 2008, the NTTA Board approved the Phase 4A schematic and environmental assessment.

Additional progress has been made through a partnership with Collin County. In 2007 Collin County awarded a contract to construct a two-lane road from U.S. 380 north to FM 428. The first portion of this road from U.S. 380 to First Street opened to traffic in November of 2007. On October 14, 2008, the rest of the two-lane road up to FM 428 officially opened to traffic. This road is expected to be the future DNT northbound service road.

North of FM 428, work is ongoing to determine the final alignment of the tollway extension.

The DNT 4A schematic is available for viewing below. (Note: These are large files and may take a few minutes to load.)
