The Crystal Valley Interchange (CVI) is a long-awaited infrastructure upgrade at I-25 and Crystal Valley Parkway in Castle Rock, Colorado. As a Castle Rock car accident lawyer, Dale G. Casares at Casares Injury Law supports efforts like this that aim to reduce traffic collisions and improve roadway safety. The project is overseen by the Town of Castle Rock, Douglas County, and the Colorado Department of Transportation (CDOT).
The new project will feature:
- A new bridge carrying Crystal Valley Parkway over I-25 with two through-lanes in each direction and improved sidewalk and trail connections.
- Construction of north- and south-bound on/off ramps to and from I-25.
- A roundabout on the east side of I-25 to improve traffic flow.
- A new bridge over the BNSF railway west of I-25.
- Realignment and reconstruction of the east and west frontage roads, including the development of a new roadway.
The estimated total cost of the CVI is around $144 million, with funding coming from developer contributions, county/town funds, and state and federal grants.
Timeline of the CVI
The final design of the CVI was completed in 2023. Groundbreaking and initial construction activity began in 2024, including preliminary work on the frontage roads and roundabout.
Other phases of the project include:
- Summer – Fall 2024 saw lane reductions on the East Frontage Road and trail closures through early 2025.
- September 2024 marked the beginning of relocation and realignment of The West Frontage Road, with an expected closure of 18 months.
- February 2025 kicked off with the staged installation of bridge girders over I-25, a project requiring some overnight closures and detours.
- Summer 2025 will feature major bridge construction over I-25.
- Fall 2025 is the expected timeline for the opening of segments of Dawson Trails Boulevard and the realigned frontage roads.
Full project completion is anticipated in 2027, including all ramps, bridges, trails, and roadways.
What to Watch Out for During Construction
With such a major project, there are many hazards that drivers should be aware of.
1. Traffic Impacts
The project is being constructed in phases to minimize disruption. Still, drivers should expect some delays. Nighttime closures on I-25 and long-term closures of the frontage roads will be necessary. Traffic shifts, flaggers, and detours will be a common sight in the area.
2. Trail and Pedestrian Access
Parts of the East Plum Creek Trail and other pedestrian routes may be closed temporarily. Trail users should watch for posted detours and plan alternate routes.
3. Noise and Night Work
Most work is scheduled for daytime hours. However, some overnight and weekend work will be required. This may increase noise levels and light usage in nearby residential areas.
4. Speed Zones and Safety
Speed limits will be reduced in active construction zones. Drivers are advised to follow posted signage and allow extra travel time. Fines and enforcement may increase to ensure safety for both workers and motorists.
5. Winter Conditions
Snow removal during construction will be managed jointly by CDOT, Douglas County, and the Town of Castle Rock. Motorists should anticipate possible delays in plowing along realigned or closed roads.
