Town moves forward on improvements to Founders/Allen intersection

It might be the most talked about intersection in Castle Rock, and Town Council last week took significant steps toward fixing it.  

The intersection of Founders Parkway and Allen Way is one of Castle Rock’s busiest. Now, design is underway on a number of improvements expected to ease congestion and increase access to Interstate 25.  

Construction is expected in 2018. Improvements will include:

•An additional eastbound left-turn lane from Founders Parkway to Allen Way

•A dedicated westbound right-turn lane from Founders Parkway to Allen Way

•An additional southbound right-turn lane from Allen Way to westbound Founders Parkway

•An additional I-25 northbound on-ramp lane

•A second northbound through-lane at Allen Way and Allen Street

Town Council on Jan. 17 approved two agreements to move the project forward. One was a design contract with engineering firm Felsburg, Holt & Ullevig. Also, because the Colorado Department of Transportation owns and operates the intersection, Council also approved an Intergovernmental Agreement with CDOT. The IGA outlines the responsibilities of both CDOT and the Town of Castle Rock for the duration of the project.

The total cost of the project is expected to be about $4.5 million. Nearly half is coming from a $2 million grant. 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, an organization of local governments that work together to establish guidelines, set policy and allocate funding in the areas of transportation, growth, and aging and disability resources.  

The Colorado Department of Transportation will allocate up to $280,000, and Douglas County will contribute $250,000 to the project. The Town will fund the remaining $1.9 million.  

Design is expected to be completed this year. Part of the design process will be to determine project phasing to minimize delay to drivers during construction. Construction is expected to begin when the federal funding is available to the Town in 2018.
