Interstate 25

From Wikipedia, the free encyclopedia.

Interstate 25 is an interstate highway in the western United States. Like other "interstates," it is commonly referred to as I-25. Its odd number indicates that it is primariliy a north-south highway. It goes from Interstate 10 at Las Cruces, New Mexico to Interstate 90 in Buffalo, Wyoming.

Notes

• The I-40 and I-25 interchange in Albuquerque, New Mexico 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. [1]
• It is the main north-south highway through Colorado, passing through Cheyenne, Wyoming, near Ft. Collins, Colorado, through Denver, Colorado, Castle Rock, Colorado, Colorado Springs, Colorado, Pueblo, Colorado and over Raton Pass into New Mexico. The I-25 corridor in Colorado is heavily urbanized, passing just east of the Front Range of the Rocky Mountains. This stretch is currently involved in a massive renovation named T-REX [2](TRansportation EXpansion) in Denver, and COSMIX [3] (Colorado Springs Metro Interstate Expansion) scheduled to begin in August 2005.
• The section between Romeroville, New Mexico and Los Lunas, New Mexico closely follows the original alignment of U.S. Highway 66, which was later shortened and realigned to run straight west from Santa Rosa, now replaced with Interstate 40.
