Interstate 25 in Colorado
Encyclopedia
In the U.S. state
of Colorado
, Interstate 25
follows the north–south corridor through Colorado Springs
and Denver
. It replaced U.S. Highway 87 and most of U.S. Highway 85 for through traffic.
Historical nicknames for this route have included the Valley Highway (through Denver
), Monument Valley Highway (through Colorado Springs
), and the Pueblo Freeway (through Pueblo). Within El Paso County
, the route has been dedicated as the Ronald Reagan Highway. In Pueblo County, the route is called John F. Kennedy Memorial Highway.
Interstate 25 is also considered to be part of the unofficial Pan-American Highway
.
Following the Santa Fe Trail
from New Mexico
, Interstate 25 enters Colorado
as a typical two-lane Interstate Highway, where its entire route in Colorado lies close to the east side of the Rocky Mountains
. The route turns from north to west-northwest as I-25 serves Wootton. After leaving Wootton, I-25 turns back up north and bypasses near the east side of the Trinidad Lake State Park
, home of the Trinidad Lake.
Trinidad
, a city near the Trinidad Lake, is the first major city that lies along I-25. For the next 30 miles (48.3 km), I-25 continues north through the rural areas of Colorado until it reaches the small city of Walsenburg
, where the business route - I-25 Bus. - junctions with U.S. Highway 160. I-25 then continues in a north-northwest direction until it bypasses the Orlando Reservoir, then turns north from there until it reaches Colorado City
. In Colorado City, I-25 interchanges with the east end of the Frontier Pathways Scenic and Historic Byway (SH 165
) at exit 74.
After leaving the city, I-25 follows in a north-northeast orientation until it reaches the St. Charles Reservoir just before entering the city of Pueblo
, with the first exit within the southern city limits of Pueblo at exit 94. The Arkansas River
in Pueblo serves as a feeder to the Lake Pueblo State Park
, home of the Pueblo Lake, which is located to the west of the western city limits of Pueblo.
After leaving Pueblo
, I-25 continues up north with the Union Pacific Railroad
line paralleling closely to the route on the right side after interchanging with Porter Draw at exit 106. By exit 119, the Fountain Creek
joins along and travels parallel with I-25, and continues all the way to the Fountain Creek Regional Park in Widefield. I-25 gradually turns from a general north direction to the north-northwest and serves the census-designated place
of Buttes at exit 122.
As soon as US 85 leaves I-25 at exit 128, I-25 enters the city limits of Fountain
. Basically, I-25 serves as the border between the western city limits of Fountain on the east side of I-25 and Fort Carson on the west side. Exit 132 (SH 16) serves the north side of the Fountain Creek Regional Park as well as the entrance to Fort Carson. At exit 135, Academy Boulevard serves Pikes Peak Community College
's Centennial campus. By the time I-25 reaches exit 138, the route enters the city limits of Colorado Springs
, where the interchange with US 24 at exit 139 serves the Evergreen Cemetery and Prospect Lake. I-25 turns west at exit 140, along with the Fountain Creek
, where it interchanges with US 85, US 87, and I-25 Bus. I-25 again turns back north again by exit 141. Exit 142 serves downtown Colorado Springs, and to the north of the city lies the Colorado College
, and is served at exit 143 - Uintah Street. After leaving Colorado Springs, I-25 enters the United States Air Force Academy
from exits 150 to 156, and goes through the east side of the territory.
I-25 leaves El Paso County
and enters Douglas County
at the county line at exit 163. I-25 then continues north through more rural areas east of the Rocky Mountains
until reaching Castle Rock
at exit 181. I-25 continues through a variety of suburban communities until interchanging with E-470
, the partial beltway of Denver
as the toll road serves the Centennial Airport
and the much larger Denver International Airport
.
After entering Arapahoe County
, I-25 interchanges with I-225, a spur that detours motorists to I-70
, at exit 200. I-25, then goes around in a general northwest direction before interchanging with US 6 at exit 209. Then I-25 curves around the west side of downtown Denver
, where it can be accessed by I-70 Bus. at exit 210. I-25 then interchanges with I-70
at exit 213 right before leaving the City and County of Denver
.
, and the Denver-Boulder Turnpike (US 36). Due to the complexity of this triangle-shaped interchange, it was known to be one of many malfunction junctions
throughout the United States
. Beyond that interchange and exit 220, I-25 slips its way through a narrow path between the Badding Reservoir (west side) and the Croke Lake (east side).
At exit 228, I-25 interchanges with the northern termini of E-470
and Northwest Parkway
at a stack interchange
, with the Larkridge Mall just to the north, served by 160th Avenue (SH 7
). As I-25 continues north, it passes through a medley of lakes and reservoirs to the east and north of Fort Collins
. Afterwards, the interstate gradually makes a north-northeast turn as it heads for the Wyoming
state line.
as early as 1944, well before the national movement toward an Interstate Highway system
.
State Highway 1
, an unpaved road, was completed between Denver
and Pueblo
by 1919. Average travel time between Pueblo and Colorado Springs
on this route was approximately 2.5 hours (or a full 8.5 hours from Pueblo to Denver). This route was upgraded with the help of the federal government to become US 85 and US 87 by 1930, now paved in concrete and shortening the travel time between Pueblo and Colorado Springs to just one hour.
The cities of Denver (in 1948) and Pueblo (in 1949) were first to begin building multi-lane highway segments along the route of what would eventually become Interstate 25. Construction follows an earlier segment of the Colorado and Southern Railway
. Denver's segment was originally known as the Valley Highway and was completed by 1958. The city of Colorado Springs followed a similar theme with their Monument Valley Freeway, begun in 1955 and completed by July 1960. Pueblo's section — the Pueblo Freeway - was complete by July 1959.
began to take shape, actual "inter-state" connections began to be made. Wyoming
came first in 1964, building a 9 miles (14.5 km) link north to Cheyenne
that was connected to Colorado
's 17 miles (27.4 km) stretch.
Linking to New Mexico
in the south would prove more problematic as the planned route had to stretch over Raton Pass
, and its accompanying 1800 feet (548.6 m) elevation change, within just 13 miles (20.9 km). Once again, US 85 and US 87 were used, but it had to be re-graded in places to meet Interstate design guidelines. Construction began in 1960, with a link to the city of Trinidad
completed by 1963. The Trinidad Segment (as CDOT now calls the Raton Pass
span) was not fully completed until 1968.
The final segment of the Colorado
portion of Interstate 25, connecting the cities of Walsenburg
and Trinidad
, was completed during 1969. This meant that four lanes of high-speed, nonstop freeway were finally open for a full 305 miles (490.8 km) from New Mexico
north to Wyoming
.
has planned and completed major improvements for the city corridors along I-25.
The first of these was Transportation Expansion
(T-REX), which widened and expanded nearly 17 miles (27.4 km) of both I-25 and the I-225 bypass in the Denver Metropolitan Area as well as adding various pedestrian and aesthetic improvements. T-REX was also instrumental in expanding Denver's RTD light rail lines to connect outlying communities beyond the city and county of Denver
, adding 19 miles (30.6 km) of new routes.
Starting in early 2004, the T-REX project was completed during 2006 at a cost of US$1.67 billion, under its projected budget and two years ahead of its originally scheduled conclusion. It has been hailed as a "model for other cities to follow" and "ahead of the curve nationally" by federal transportation and transit authorities.
As T-REX began to wrap up, CDOT's next major effort began with Colorado Springs Metro Interstate Expansion (COSMIX). It could be argued that COSMIX was even more important to Colorado's interests than T-REX had been, since the Colorado Springs corridor of I-25 had seen immense growth over the past four decades. Originally carrying around 8500 vehicles per day in 1960, usage of the former Monument Valley Freeway had grown to an average of 100,000 vehicles per day by 2005.
The major goals of COSMIX, which began in 2005 and was completed during December 2007, were a general expansion and widening of the corridor to three lanes in each direction throughout the city, as well as the reconstruction of two main interchanges (at Bijou Street near downtown Colorado Springs
, and at Rockrimmon Boulevard and North Nevada Avenue in the city's growing north side).
Though CDOT's role in COSMIX was complete, the City of Colorado Springs continued its own independent project to rebuild the Cimarron Street (US 24) bridge and interchange. This work was functionally complete (allowing limited traffic) by May 2008, with full completion achieved by September 2008.
has begun work toward expanding the I-25 corridor between Colorado Springs
and Denver
, as well as the corridor between Denver and the city of Fort Collins
(the "North Forty" project, in reference to the 40 miles (64.4 km) of highway north of Denver that are affected). In both cases, growth of suburbs and smaller communities (such as Castle Rock
and Longmont
) have necessitated expansion much like that of T-REX or COSMIX (though on a less ambitious scale).
Reconstruction of the aging Trinidad Segment is also underway, aimed mainly at rebuilding bridges and upgrading the highway to modern Interstate design standards. Construction began with demolition and reconstruction of the bridges during 2007, and the remaining viaduct reconstruction is currently scheduled to be completed by August 2009.
A New Pueblo Freeway project is in the planning stages. Currently, the draft includes an expansion to six lanes (three each direction), numerous interchange improvements, and enhancements to pedestrian routes and public parks along the corridor. Public review of the final plan is scheduled for the Fall of 2008.
