'''Interstate&nbsp;25''' ('''I-25'''), also known as the '''Pan-American Freeway''', 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|I-10]] at [[Las Cruces, New Mexico]] (approximately {{convert|25|mi|km|disp=sqbr}} north of [[El Paso, Texas]]) to [[Interstate 90|I-90]] in [[Buffalo, Wyoming]] (approximately {{convert|60|mi|km|disp=sqbr}} south of the [[Montana]]–Wyoming border).<ref name="Google">{{google maps |url = https://maps.google.com/maps?f=d&hl=en&geocode=18418043515694651916,32.264485,-106.731215&saddr=I-25+N+%4032.264485,+-106.731215&daddr=44.365526,-106.689005&mra=mi&mrsp=1,0&sz=15&sll=44.365802,-106.681795&sspn=0.013867,0.028925&ie=UTF8&ll=39.300299,-106.303711&spn=15.355455,29.619141&z=5 |title = Overview Map of I-25 |access-date = February 15, 2008 }}</ref> It passes through or near [[Albuquerque, New Mexico]]; [[Pueblo, Colorado|Pueblo]] and [[Denver]] in Colorado; and [[Cheyenne, Wyoming|Cheyenne]] and [[Casper, Wyoming|Casper]] in Wyoming. The I-25 corridor is mainly rural, especially in Wyoming, excluding the [[Albuquerque metropolitan area]] and the [[Front Range urban corridor]] from Pueblo to Cheyenne.

The part of I-25 in Colorado passes just east of the [[Front Range]] of the [[Rocky Mountains]]. That stretch was involved in a large-scale renovation named the [[Transportation Expansion Project|Transportation Expansion (T-REX) Project]]<ref>{{cite web |url=http://www.trexproject.com/ |title=T-REX Fashion & Clothing Project &#124; |access-date=July 2, 2005 |url-status=dead |archive-url=https://web.archive.org/web/20140502225428/http://www.trexproject.com/ |archive-date=May 2, 2014  }}<!--archive link from 2014 is for a fashion website, and earlier archives failed to capture.--></ref> in Denver and the Colorado Springs Metropolitan Interstate Expansion (COSMIX).<ref>{{cite web |url = http://www.cosmixproject.com/ |title = COSMIX Project Home Page |publisher = Cosmixproject.com |access-date = November 27, 2011 |url-status = dead |archive-url = https://web.archive.org/web/20100114182606/http://cosmixproject.com/ |archive-date = January 14, 2010 }}</ref> These projects, and others in New Mexico, were necessary because these stretches of I-25 were originally inadequately designed and constructed (the pavement was deteriorating rapidly) and also because urban areas, like Albuquerque, Colorado Springs, and Denver, 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 New Mexico and Colorado.
