It continues southeast toward Sulphur Springs, where it shares a concurrency with State Highway 154 and the old routing of US 67, and intersects I-30 on the south side of town.

[2] In 1917, the routing was proposed from the Oklahoma state line at Denison, south on present day U.S. Highway 69 through Whitewright into Greenville.

On June 17, 1918, the segment from Gilmer to Longview had yet to be built, so the road was rerouted over the current US 271 and US 80 routes through Gladewater, Texas.

On February 8, 1933, it was extended to begin in Ladonia via the present day State Highway 50.
