The highway serves the communities of Monument and Palmer Lake and the unincorporated areas of Douglas and El Paso counties.

The south segment in El Paso County is 4.739 miles (7.627 km) long and it begins at Jackson Creek Parkway and heads west.

The highway then enters Sedalia and terminates at a junction with SH 67 (Manhart Avenue), facing East Plum Creek.

[1] The route was established in the 1920s, when it connected U.S. Highway 87, now Interstate 25, to Sedalia.

The road was extended to replace SH 50 (now deleted) due to confusion with U.S. Highway 50.
