Improvements are coming to the Four Corners intersection, where Founders Parkway, Fifth Street, State Highway 86 and Ridge Road meet, to increase safety, reduce congestion and keep you moving throughout Castle Rock.
The Four Corners improvements project includes intersection reconstruction, roadway widening, signal upgrades and accessibility improvements. This work will help alleviate roadway congestion, increase mobility for vehicular, pedestrian, and bicycle traffic and create a safer experience for all travelers at this major intersection.
Once completed, the project will feature the following elements:
- Additional through lane in all directions
- Double dedicated left-turn lanes on northbound Ridge Road and southbound Founders Parkway
- Upgrades to the traffic signal
- Crosswalk improvements and trail connections
Construction is expected to begin Wednesday, Oct. 4. Throughout the duration of the project, please watch for changing traffic patterns and daytime and nighttime lane closures. Access impacts to local businesses may be required intermittently. The project team will maintain access, although a short detour may be required. Please plan for some delays while traversing this intersection. Signs along the roadside will provide the most updated information.
This project is a collaborative effort between the Town of Castle Rock, Douglas County and the Colorado Department of Transportation. Construction is anticipated to be complete in late 2024.
