Colorado’s Interstate 25 will experience nighttime closures south of Castle Rock this week as construction crews install bridge structures for the Crystal Valley Interchange Project.
The project, a collaboration between the Town of Castle Rock, Douglas County and the Colorado Department of Transportation, aims to enhance traffic flow and safety.
It includes a new bridge over I-25, West Frontage Road and BNSF Railway tracks. Construction is expected to be completed by early 2027.
Closures will occur in phases:
- 10:30 p.m. – 5:30 a.m., March 9-10: Southbound I-25 will be fully closed between Exit 181 (Plum Creek Parkway) and Exit 174 (Tomah Road). Traffic will be rerouted to East Frontage Road.
- 10 p.m. – 5 a.m., March 11-12: Northbound I-25 will be fully closed from Exit 174 to Exit 181, with traffic detoured to East Frontage Road.
- Additional closures will affect Crystal Valley Parkway and West Frontage Road at varied times.
Crews will use two large cranes to install 53 bridge girders, the largest measuring 130 feet and weighing 80,000 pounds.
Residents said the project will ultimately improve access and reduce congestion despite temporary inconveniences. According to a report from Denver 7 News. Motorists are advised to use Colorado State Highway 83 as an alternate route and check COtrip.org for updates.
