Roadwork planned for Founders Parkway in Castle Rock

Founders Parkway and Allen Way in Castle Rock is slated for construction to reduce intersection congestion.

The Colorado Department of Transportation (CDOT) could start roadwork on the Founders Parkway and Allen Way intersection in Castle Rock as soon as next month.

Following public open houses and meetings this summer, CDOT presented its plan for the intersection and other roadwork. The plan, agreed upon by The Town of Castle Rock and CDOT, involves adding another eastbound left-turn lane so that there will be more space for cars waiting to turn left from Founders Parkway onto Allen Way. Traffic turning left from the King Soopers side, or from the businesses north of Founders Parkway, would not be impacted.

The additional eastbound left turn lane at Founders Parkway and Allen Way will not only help reduce intersection congestion, but it will also help keep waiting traffic from stacking up into the eastbound through lanes.

The intersection construction is part of broader improvements CDOT has planned for Founders/Meadows Parkway between Factory Shops Boulevard and Woodlands Boulevard that include pavement replacement and drainage improvements. The work will occur as two projects, starting with eastbound Meadows Parkway where the I-25 on-ramp will be widened to two lanes.

Work could begin on Meadows Parkway as early as next month. Funding and a timeline for phase two, including the Founders/Allen intersection, has not yet been determined.

Please note: This work is separate from The Town’s North Meadows Extension project, which will provide a new western access to I-25 about one mile north of the Founders/Meadows Parkway interchange.
