Dallas North Tollway
Complex Projects. Exceptional Outcomes
Sinacola was the successful low bidder on two North Texas Tollway Authority (NTTA) projects for the expansion of the Dallas North Tollway (DNT) north of US 380. The projects extend the DNT by approximately six miles through Prosper and Celina—two of the fastest-growing cities in Texas, situated in the fastest-growing county in the country. This expansion will significantly improve regional mobility, enhancing connectivity from northern Celina to downtown Dallas.
