US 36 Wildlife Crossings Proposal Update

Recording now available. Survey open.

Boulder County has started investigating the feasibility of building wildlife crossing structures on US Highway 36 between Boulder and Lyons, specifically between Lefthand Canyon Drive and State Highway 66.

Parks & Open Space staff recently hosted a public meeting for residents to receive the latest information, ask questions, and express concerns. The recording and a two-question survey are now available on the project webpage.

The webpage also includes past public presentations on the importance of wildlife crossings and the specifics of this project and an email sign up link to receive updates throughout the project.

For additional questions, please contact project manager Susan Spaulding, Boulder County Parks & Open Space Environmental Resources Sr. Specialist at sspaulding@bouldercounty.gov
