Colorado State Highway 23


State Highway 23 is a long state highway in the northeastern corner of Colorado. The southern terminus is at U.S. Route 385 in Holyoke, it then travels northeast through Amherst to its northern terminus at the Nebraska state line where it becomes Nebraska Highway 23.

Route description

The route begins at US 385. After sixteen miles of crossing various roads without entering any incorporated cities, it exits Phillips County and enters Sedgwick County. About a mile later, it reaches the Colorado-Nebraska state line and becomes Nebraska Highway 23.

History

The route was formerly numbered as SH 176. However, it was changed to match the Nebraska highway number at its northeast end because both SH 176 and I-76 traversed through the same general region of the state.
