Northwest Highway is a major highway/road in the Dallas-Fort Worth Metroplex area of Texas.

The highway runs through Southlake and leaves SH 114 onto the Grapevine business route, Bus.

At the Dallas-Tarrant county line, the highway's name becomes the John W. Carpenter Freeway, into Irving.

The highway crosses the President George Bush Turnpike and leaves 114 shortly after this.

After the Dallas North Tollway intersection, Northwest Highway runs past Preston Hollow (whose town hall was located on NW HWY before being annexed by Dallas in 1945) [3] and then forms the northern border of University Park and interchanges with US 75 near Northpark Mall.

Loop 12 leaves the highway to the south just northeast of White Rock Lake where the Spur 244 designation begins.
