The Grayson County Tollway study will examine the possible extension of the Dallas North Tollway from FM 121 south of Gunter to US 75 near Denison. The project would extend the proposed tollway 33 miles and provide traffic relief to US 75. Dallas-Fort Worth is projected to expand north and this project would accommodate that shift, provide an alternative for truck traffic and provide easier access to Sherman, Denison and Lake Texoma.

The project will also increase regional mobility and connect the Sherman-Denison metropolitan planning area with the Dallas-Fort Worth metropolitan area.

The study will identify and evaluate potential alignments for expansion and examine the potential environmental impacts.
