Construction on the I-25 Express Lanes is in full swing!
By the end of 2019, the I-25 and Colorado Highway 402 interchange will undergo substantial changes, resulting in a new and improved interchange. To support reconstruction, the I-25 North Express Lanes Project team will close eastbound and westbound CO 402 under I-25 for 120 days. Beginning the night of Monday, June 24, CO 402 will be fully closed from the southbound I-25 on- and off-ramps to the new Southeast Frontage Road. Once completed in October, the new configuration at CO 402 will be fully operational, and future impacts at this interchange will be minimal.

BackgroundInterstate 25 is the primary north-south interstate route in Northern Colorado and is part of the National Freight Corridor. This interstate is a primary route for commuters, travelers and freight and the average daily traffic count in Northern Colorado is over 75,000 vehicles per day. Over the past 20 years, Northern Colorado has seen a 425% population increase. With that, comes increasing travel demand as well as needed maintenance and repairs to this corridor. With the population continuing to rise, neglecting needed improvements to this section of the corridor poses traffic congestion and safety issues, and negatively impacts local and regional economies.
2016 TIGER Grant Award & North I-25 Express Lanes Project
- CDOT recently awarded $15M in Transportation Investment Generating Economic recovery (TIGER) funds to improve I-25 between SH-14 (Mulberry) and SH-402 (South Loveland)
- Helps CDOT and local agencies reach $237M for expansion
- Improvements will increase capacity by adding an Express Lane (managed lane) in both directions, replace four aging bridges and widen an additional four bridges
- Total project cost is $237M
- Improves access to regional transit
- Improves regional bus transit performance by reducing each total trip time by 15 minutes by adding new bus slip ramps from I-25 to a new Park and Ride at Kendall Parkway
- Creates new pedestrian and bicycle connections under I-25 at Kendall Parkway
- Helps connect regional trails under I-25 and serve as a wildlife corridor
- Local matching funds plus TIGER grant award accelerates I-25 improvements by 15 years
- Construction estimated to begin early 2017 and be completed by December 2020
- Express lanes (managed lanes) include toll, high-occupant vehicle, and transit uses to reduce congestion and delay, and improve traveler safety
In 2013, an I-25 Coalition was formed to help manage and accelerate improvements to the corridor. Six Northern Colorado communities, Weld and Larimer Counties, CDOT, Chambers of Commerce and private businesses have all been collaborating to help bring these improvements to fruition. Local agencies and private development committed to $25M in matching funds for this project.
Local/Regional Efforts Made to Date to Accelerate Improvements to I-25
Private and local contributions: ($25M total)
|City of Loveland||$2M|
|McWhinney (private developer)||$6M|
|City of Fort Collins||$2.25M|
|Town of Berthoud||$500K|
|Town of Johnstown||$1M|
|Town of Timnath||$500K|
|Town of Windsor||$1M|
The I-25 Coalition has grown steadily, with a current distribution list of almost 90 including representatives from Adams, Larimer and Weld counties, Berthoud, Broomfield, Dacono, Erie, Firestone, Fort Collins, Frederick, Johnstown, Loveland, Mead, Northglenn, Timnath, Thornton and Windsor as well as CDOT, businesses and other interested agencies. The Coalition's primary goal is to accelerate construction of a third lane in each direction of I-25 as identified in the I-25 North Project (from State Highway 6 to State Highway 14). Capacity improvements to the I-25 Corridor in Northern Colorado will address current and forecast congestion and safety issues posed by growing traffic demand in the region.

Long Range Plans for I-25
- The I-25 North Environmental Impact Statement was adopted in 2011. This multi-year, multiple-agency transportation and environmental planning effort identified roadway capacity and transit needs and solutions for the northern I-25 Corridor.
- Ultimate improvements include capacity widening, interchange redesign, and commuter rail
