Overnight closure of southbound I-25 in Castle Rock as work continues on new interchange

As crews continue working on signs for the new Castle Rock Parkway, another overnight closure of southbound Interstate 25 is necessary.

Here’s what to know if you travel I-25 at night next week:

• The full closure is southbound I-25 between Happy Canyon Road and Founders/Meadows Parkway. It will be from 11 p.m. Monday, May 16, to 4 a.m. Tuesday, May 17

• The detour is Happy Canyon Road west to U.S. Highway 85, then south to Meadows Parkway and east again to I-25. Please be aware, the new Castle Rock Parkway will also intersect with U.S. 85, so there will be construction along the detour route. Please drive safely.

• Lane closures are also part of this overnight work. Double lane closures will be in place prior before and after the full closure Monday night.

For now, crews are just installing the sign structures and moving the sign for the Founders Parkway exit. The signs for Castle Rock Parkway will be placed closer to the opening of the roadway later this summer. The full closure of southbound I-25 is necessary for the safety of workers and the traveling public.

As with any construction project in Colorado, this schedule depends on weather, and could change. For the most current information, stay tuned to message signs in the area and to the Town’s social media – or @CRgov on Twitter.

Castle Rock is a growing community, and the Town is preparing for that growth with its largest transportation project ever.

The 2-mile North Meadows Extension will help improve operations at the current Founders/Meadows Parkway interchange with I-25 and the intersection of Meadows Parkway and U.S. 85. It will also provide a second northern access for residents on the west side of Town.

The project is the Town’s No. 1 transportation priority. It is a partnership among the Town, Douglas County and the Colorado Department of Transportation, with additional financial support from Castle Rock Development Co. Learn more at
