Intersection of Founders Parkway and Allen Way
With big projects, come big impacts. Founders Parkway and Allen Way is one of the busiest intersections in Castle Rock. Improvements in this area are vital to the safety and mobility of the Town.
The biggest impact of the project is currently the closure of Allen Way. While we’re working to minimize this impact, we have encountered some delays. Allen Way will remain closed until approximately Friday, Sept. 20. We apologize for this additional inconvenience.
Businesses will remain available by taking Front Street to Allen Street. Stay up to date on this road project by checking here for updates and closures. To report a concern, call the Public Works project hotline at 720-733-2460 and leave a detailed message.
The intersection of Founders Parkway and Allen Way is one of the busiest in Castle Rock. An effort to improve that intersection is underway. The goal of the improvements is to ease congestion and increase access to Interstate 25.

In 2015, the Colorado Department of Transportation, which owns and operates the Founders Parkway corridor, reconstructed the concrete on Founders Parkway. However, CDOT did not have the funding at the time to improve the intersection at Allen Way.
Hearing driver concerns, the Town applied for federal funding in 2015 when CDOT reconstructed the concrete on Founders Parkway but did not have the funding to improve the intersection at Allen Way. The grant was awarded to the Town through the Denver Regional Council of Governments.
Improvements will include:
- additional eastbound left-turn lane from Founders Parkway to Allen Way
- dedicated right-turn lane from Founders Parkway to Allen Way
- additional southbound right-turn lane from Allen Way to westbound Founders Parkway
- additional I-25 northbound on-ramp lane
- second northbound through-lane at Allen Way and Allen Street
Town Council on June 18, 2019 approved a construction contract with Noraa Concrete Construction Corporation, as well as an intergovernmental agreement with CDOT. Work at this intersection is expected to begin in July and take approximately 90 days to complete.
