• An interlocal agreement (lLA) covering right of way, utility services and northbound service road construction was signed in October 2003 by the NTTA, Collin County and the Town of Prosper. The agreement covers DNT Phase 4A.

• Commissioners courts in Collin and Denton counties approved resolutions in January 2005 designating a preferred alignment along the Denton/Collin county line in Phase 4B. In May 2008, Collin County rescinded its resolution.

• The NTTA began preliminary route studies, schematic design work, environmental documentation and public involvement for Phases 4A, 4B and 5A of the DNT extension project in November 2007. That work is ongoing.

• The NTTA held a Phase 4A public hearing in July 2008 in Prosper. • On September 17, 2008, the NTTA Board of Directors approved

the Phase 4A schematic and environmental assessment.• The DNT Phase 4A (U.S. 380 to FM 428) northbound service

road opened to traffi c in 2008 as a bi-directional two-lane facility.• On March 16, 2009, the NTTA Board approved an expansion of

the DNT 4B/5A (FM 428 to FM 121) study area to the west and the north. The expansion captures more of Denton and Grayson counties and a small portion of southeast Cooke County, which will enable the NTTA to identify and preserve right of way for the DNT corridor.

• The DNT extension north of U.S. 380 is divided into two projects: – Phase 4A (U.S. 380 to FM 428):

• Staff has developed a memorandum of understanding (MOU) to serve as the basis for amendments to the DNT Phase 4A ILA. The MOU is under review.

– Phase 4B/5A (FM 428 to FM 121):• On June 3, 2010, the System Projects and Operations Com-

mittee received a briefi ng on the outcome of the public meet-ings and stakeholder meetings as well as the status of the alternatives analysis.

• A fourth round of stakeholder work group meetings was held during the third week of May 2010. The results of the March 2010 public meetings and comments were reviewed.

• The NTTA Board of Directors is expected to make a decision on a locally preferred alternative in July 2010.

• Conduct a sketch-level toll feasibility study for Phase 4A• Continue the environmental study for Phase 4B/5A preferred

alignment alternative

• The DNT Phase 4 corridor is planned to extend the tollway north from U.S. 380 to the Collin/Grayson county line. The DNT Phase 5A corridor is expected to extend the DNT from the Collin/Grayson county line to a terminus to be determined upon route selection.

• Project limits: – Phase 4A (approximately six miles) – U.S. 380 to FM 428 – Phase 4B – FM 428 extending north to the county line (actual length and terminus to be determined upon route selection)

– Phase 5A – extension north of the county line (actual length and terminus to be determined upon route selection)

• Project length: To be determined• Estimated project cost: To be determined• Opening date: To be determined

The Dallas North Tollway (DNT) extension is expected to extend north from U.S. 380, providing a link between downtown Dallas and fast-growing cities in Collin and Denton counties.
