After crossing a railroad, the highway stops as Eaton Ave as it exits Delta and enters farmland.

[2] It then continues southward through large rectangular fields until it meets D Road, where the route abruptly turns west.

[2] It then turns south and east abruptly before meeting US 50 Business a short distance before meeting US 50 in Olathe at its east end.

The route was established in 1939, when it began at SH 65 (now deleted) south of Delta and continued east through Olathe and looped northeastward back to US 50.
