St Vrain Trail Extension

General Description of the project:

The Town of Lyons applied for and received CDOT funding for building a multimodal trail from the US-36 & McConnell Drive intersection to the US-36 & SH 66 junction.   The project is expected to be completed at the end of July 2025.  The high-level scope of the project will include approximately:

•    1600’ of concrete trail, 10’ wide

•    1900’ of crusher fine trail, 10' wide

•    Two concrete box culverts

•    One steel bridge

•    Fencing

May 28, 2025  Update: Construction of the trail is nearing completion. Over the next few weeks the contractor will install fencing, railing, signage, and trail markings. These components are critical safety features, and as a result the trail will not be opened for public use until installation is complete. Please continue to avoid walking the trail until construction is completed. 

April 10 2025 update:  The concrete trail West of the Highland Ditch bridge is nearing completion. Construction activities for the remainder of April and beginning of May will include finishing the trail, grading shoulders, installing railing/fencing, and planting seed in areas with exposed earth. Trail is still not open for public use. Please continue to avoid walking the trail for your safety and the safety of our crews.
