We worked with the Town of Windsor, Colorado to designed multimodal improvements on 11th Street from the Greeley No. 2 Canal to Sagewood Drive. Improvements included new bicycle lane signing, pavement marking changes, existing rectangular rapid flashing beacon (RRFB) signal modifications, raised medians, and intersection improvements along the corridor including the Main Street (Colorado Highway 392) intersection. This project developed out of the 2020 Transportation Master Plan Update and proposed to add new bike facilities in a gap that exists along 11th Street.

The Colorado Department of Transportation Local Agency process was followed with the successful completion of three clearances.  The team worked with the city to minimize design impacts and deliver the goals of the project.  Throughout the project, our team hosted a variety of public involvement including a virtual open house, and pop-up events at the community recreation center and high school football game to engage a wide cross section of the public.

Additional scope for the project included a Traffic Impact Study (TIS) to evaluate different concepts for the intersection of Ash and 11th Streets. We compared the circulation and safety for both a right in right out design on the east side of the intersection as well as concept design for a roundabout. Through the process, it was determined that the right in, right out was the best solution for today, while having developed a design for the roundabout that could be used for further grant applications in the future.

We also helped the Town of Windsor develop a grant application that was successful in securing $450,000 of Multimodal Transportation and Mitigation Options Funding to support construction.
