It heads due east from here, passing just north of the northernmost tip of Country Club Lake.

Just after this lake, the highway turns southeast, then back to the east, bringing it onto the section line that it will follow for the remainder of its route.

At this time, the highway began at SH-40 (present-day US-177) west of Tryon, and ended at SH-18 south of Agra.

The highway was extended west to its current western terminus east of Guthrie on June 4, 1955.

[7] The western half of the highway was not shown on the official state map at all until the 1981 edition, which showed it as paved.
