Major I-25 Closures In Colo. As Castle Rock Bridge Work Begins

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:

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.
