Editing Interstate 25 (section)

{{Main|Interstate 25 in Colorado}}
I-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, Colorado|El Paso County]] is named the [[Ronald Reagan Highway]], and, through [[Pueblo, Colorado|Pueblo]], it is named the John F. Kennedy Memorial Highway. 

In the [[Federal-Aid Highway Act of 1973]], a transcontinental highway was named after President [[Dwight D. Eisenhower]], in commemoration of the route of the [[1919 Motor Transport Corps convoy|US Army's 1919 convoy]]. This route, rather than following a single highway, spans several, including I-25 in Denver. This combination of routes was intended to approximate the original 1919 convoy route.<ref>{{cite web|url=https://www.fhwa.dot.gov/infrastructure/ddehwy.cfm|title=Dwight D.

The designation of this highway, while clear in intent, has not seen widespread adoption in terms of signage or recognition, likely due to the irregular nature of the route. Despite this, a commemorative sign was installed in 1986 in the tourist information center off [[Interstate 70|I-70]] in [[Kansas City, Kansas]].<ref>{{cite web|url=https://www.fhwa.dot.gov/infrastructure/ddehwy.cfm|title=Dwight D.

Eisenhower System of Interstate and Defense Highways".<ref>{{cite web|url=https://www.fhwa.dot.gov/infrastructure/ddehwy.cfm|title=Dwight D.

I-25 enters [[Colorado]] {{convert|14|mi|km}} south of the city of [[Trinidad, Colorado|Trinidad]]. It is the main north–south route through Colorado with a length of {{convert|300|mi|km}}. The Interstate exits Colorado in the north about {{convert|8|mi|km|spell=in}} 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, Colorado|Colorado Springs]], Pueblo, [[Fort Collins, Colorado|Fort Collins]], and [[Greeley, Colorado|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 Space Force Base]], the [[Cheyenne Mountain Complex]] headquarters of [[NORAD]], [[Fort Carson]], [[Peterson Space 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|Pueblo County]] 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]].
