Interstate 25 (I-25) is an Interstate Highway in the western United States. It is primarily a north–south highway. I-25 stretches from Interstate 10 at Las Cruces, New Mexico, (approximately 25 miles (40 km) north of El Paso, Texas), to Interstate 90 in Buffalo, Wyoming, (approximately 60 miles (97 km) south of the Montana/Wyoming border).[1]

Interstate 25 is the main north–south expressway through Wyoming, Colorado, and New Mexico. From north to south, it passes through or near Casper, Wyoming; Cheyenne, Wyoming; Fort Collins, Colorado; Denver, Colorado; Colorado Springs, Colorado; Pueblo, Colorado; Raton, New Mexico; Las Vegas, New Mexico; Santa Fe, New Mexico; Albuquerque, New Mexico; Socorro, New Mexico; Truth or Consequences, New Mexico and Las Cruces, New Mexico. The I-25 corridor is mainly rural, especially in Wyoming, excluding the Albuquerque, Pueblo, Colorado Springs, and the Denver areas. The part of I-25 in Colorado passes just east of the Front Range of the Rocky Mountains. That stretch was recently involved in a large-scale renovation named the T-REX[2] (TRansportation EXpansion) in Denver, and the COSMIX[3] (Colorado Springs Metropolitan Interstate Expansion). These projects and others in New Mexico were necessary because these stretches of I-25 were inadequately designed and constructed originally (the pavement was deteriorating rapidly), and also because urban areas like Denver, Colorado Springs, and Albuquerque had tripled and quadrupled in population much earlier than anyone had anticipated back in the 1950s and 1960s. Major highway work for the T-REX project ended on August 22, 2006. The COSMIX project was completed in December 2007. Several other smaller improvement projects for I-25 are still ongoing within Colorado and New Mexico.

New Mexico

Interstate 25 begins at Interstate 10's exit 144 in Las Cruces, just south of the New Mexico State University campus.[5] I-25 is concurrent with U.S. Route 85 at this point, and carries this concurrency for the entire length of its run in New Mexico. Immediately, three exits provide access to the city, including one for U.S. Route 70.[6] When I-25 reaches Truth or Consequences, it is parallel to Elephant Butte Lake State Park.[7] From Las Cruces to Santa Fe I-25 follows the route of El Camino Real de Tierra Adentro.[8]

As I-25 nears Albuquerque, it has interchanges with highways such as U.S. Route 380 and a concurrency with U.S. 60.[9] Further north, State Road 6, former U.S. Route 66, meets up with I-25 in Los Lunas.[10] Through Albuquerque I-25 is named the Pan American Freeway and there are frequent exits to city streets.[11][12]:248 A major interchange with Interstate 40 (which is styled as the Coronado Freeway in the city) is named the Big I.[12]:248[13] It was given an honorable mention by the United States Department of Transportation and the Federal Highway Administration for excellence in urban highway design in 2002.[14]

Leaving Albuquerque to the north, I-25 curves to the northeast as it approaches Santa Fe.[15] Continuing 'northbound' at Santa Fe, I-25 heads southeast for approximately 45 miles (72 km) traveling through the Santa Fe National Forest and crossing Glorieta Pass (elevation 7,452 feet (2,271 m)).[16] It turns north again at Blanchard toward Las Vegas.[17] The highway maintains a north and northeast orientation as it leaves New Mexico traversing Raton Pass (7,798 feet (2,377 m)[18]) and enters Colorado. From Santa Fe to Trinidad, Colorado I-25 approximates part of the route of the Santa Fe Trail.[19] For its entire length in the state, I-25 shares its alignment with US-85, although US-85 is unsigned.

Colorado


Interstate 25 has many nicknames through the state's larger cities. In Denver it is called the Valley Highway, as the highway parallels the course of the South Platte River throughout the downtown area and is often sunken below ground level. The section in El Paso County is named the Ronald Reagan Highway, and through Pueblo it is named the John F. Kennedy Memorial Highway.


I-25 enters Colorado 14 miles (23 km) south of the city of Trinidad. It is the main north–south route through Colorado with a length of 300 miles (480 km). The Interstate exits Colorado in the north about 8 miles (13 km) south of Cheyenne, Wyoming. I-25 serves all the major cities in Colorado that are east of the Rocky Mountains, such as Denver, Colorado Springs, Pueblo, Fort Collins, and Greeley. For the entire distance in Colorado, from the north to the south, the Rocky Mountains are clearly visible.

There are also several important military and air bases and institutions along this route, such as Buckley Air Force Base, the Cheyenne Mountain headquarters of NORAD, Fort Carson, Peterson Air Force Base, and the United States Air Force Academy.

I-25 crosses the Palmer Divide between Denver and Colorado Springs, providing some of the highway's most scenic views of the Rocky Mountains and its foothills. Blizzards and high winds on this stretch (particularly over Monument Hill) are notorious for causing traffic problems during the winter months.

The section of I-25 that is between the northern border of Pueblo County, Colorado, and the New Mexico state line is named the "John F. Kennedy Memorial Highway", in honor of President Kennedy's support of water resources development in the Arkansas River Valley.

Wyoming


I-25 enters Wyoming 8 miles (13 km) south of the state capital city, Cheyenne. After traveling through Cheyenne, Interstate 25 continues north to Douglas, Wyoming, passing many plateaus and also railroad tracks. Commonly, very long trains can be seen slowly moving alongside this highway. Around Douglas, this interstate highway curves somewhat to the west toward Casper. Once through Casper, I-25 turns due north, and it goes as far as Buffalo, Wyoming, where it ends at an intersection with Interstate 90. Then, Interstate 90 provides the connection to Montana.

History

The section between Romeroville, N.M., and Los Lunas, New Mexico, closely follows the original alignment of U.S. Highway 66, which was later shortened and realigned to run due west from Santa Rosa. Now, that has been replaced with Interstate 40.
