North Texas Tollway Authority; Future Expansion
The future Dallas North Tollway (DNT) Phase 4 project will extend the tollway 13.7 miles north of US 380. When this extension is complete, it will provide a direct link between downtown Dallas and growing areas in Collin, Denton and Grayson counties. The project is currently in the planning and design phase.
 
The NTTA Board of Directors chose an alignment for the Phase 4 extension that straddles the Collin-Denton county line from FM 428 in Collin County to the Grayson County line. The county alignment provides a greater economic development benefit for most of the region, requires less right of way and follows an existing county road system.
 
Initially, there was an additional section identified as part of this extension. It was referred to as Phase 5A and would have extended the DNT from the Grayson County line to FM 121 in Grayson County.
