Interstate 25 - Weld County (Southbound)

Interstate 25 is the primary north-south freeway route along the foothills of the Front Range in the state of Colorado. Since the freeway covers nearly 300 miles of the Centennial State, the page has been split into the following segments:

Interstate 25/U.S. 87 South
The freeway departs from Larimer County and enters Weld County. Photo taken 09/05/04.
Southbound Interstate 25/U.S. 87 next reaches Exit 250, Junction Colorado 56. The original two-lane U.S. 87 is the frontage road to the east of Interstate 25, and some older bridges may be seen along this route. Now U.S. 87 is subsumed into Interstate 25, and the four-lane freeway has replaced the old alignment. Photo taken 09/05/04.
The next exit along southbound Interstate 25 is Exit 245, Junction Weld County Route 34, Walker Avenue. Use Walker Avenue west to the community of Mead, which lies at the intersection with Third Street. Photo taken 09/05/04.

The next exit along southbound Interstate 25 and U.S. 87 is Exit 243, Junction Colorado 66. Colorado 66 travels east to Platteville (Junction U.S. 85) and west to Lyons (Junction U.S. 36). Use Colorado 66 west to Hygiene. Photo taken 09/05/04.
Southbound Interstate 25 and U.S. 87 reaches Exit 243, Junction Colorado 66. To the west, Colorado 66 also serves the northern portion of the city of Longmont; the city center lies at the intersection of U.S. 287 and Colorado 119 several miles southwest of this interchange (Exit 243). Prior to the extension of U.S. 36 over the Denver-Boulder Turnpike in 1967, the section of what is now U.S. 36 between Lyons and Estes Park was part of Colorado 66. The westernmost section of Colorado 66 between Estes Park and Rocky Mountain National Park (Deer Ridge Junction) also became part of U.S. 36 by the late 1970s. Photo taken 09/05/04.

The next exit along southbound Interstate 25 and U.S. 87 is Exit 240, Junction Colorado 119 (Diagonal Highway). Colorado 119 travels southwest to Boulder, then enters the foothills of the Front Range before ending at U.S. 6 in Clear Creek Canyon. Photo taken 09/05/04.
Southbound Interstate 25 and U.S. 87 reach Exit 240, Junction Colorado 119 (Diagonal Highway), in Longmont. Just in ten years, the services and amenities at this exit have grown with additional restaurants and service stations. Colorado 119 is a major route leading west and south from Interstate 25 to Boulder, and this interchange can tighten with traffic at times due to the amount of congestion and services located here. For travelers of southbound Interstate 25, this exit is the best way to reach Boulder. Photo taken 09/05/04.
