Interstate 25 (I-25) is a major Interstate Highway in the western United States. It is primarily a north–south highway, serving as the main route through New Mexico, Colorado, and Wyoming. I-25 stretches from Interstate 10 at Las Cruces, New Mexico (approximately north of El Paso, Texas), to Interstate 90 in Buffalo, Wyoming (approximately south of the Montana–Wyoming border). It passes through or near Albuquerque, New Mexico; Colorado Springs, Colorado; Denver, Colorado; and Cheyenne, Wyoming. The I-25 corridor is mainly rural, especially in Wyoming, excluding the Albuquerque, Pueblo, Colorado Springs, and Denver metropolitan areas.
