The Dallas North Tollway is being expanded to link downtown Dallas to Collin, Denton and Grayson counties.

The North Texas Tollway Authority is extending the tollway with construction of a new four-lane bridge over U.S. 380. Construction began in February 2020, according to Michael Rey, media relations manager.

This project will extend the tollway 13.7 miles north of US 380, according to NTTA project documents.
Once the bridge is complete, the NTTA will add another four-lane segment of tollway between US 380 and FM 428 in Celina, officials said. This portion of the project is still under design, and design work may not finish until 2024, Rey said.

Construction on a two-lane frontage road from FM 428 to the Grayson County line is part of the project. The NTTA Board of Directors selected Mario Sinacola and Sons Excavating for construction of the frontage road, and CONSOR Engineering for construction management.

Coordination with stakeholders and partners is ongoing, the documents indicate. Crews continue to work on the DNT extension project over US 380 alongside environmental engineering work.

Rey said completion is scheduled for 2023.
