128th Avenue, Pecos Street, and Huron Street Project Summary
The City of Thornton has conducted a study to determine the most appropriate bicycle facility type on the three following corridors: 128th Avenue from I-25 to York Street, Pecos Street from Milky Way to 92nd Avenue/Thornton Parkway, and Huron Street from 84th Avenue to 88th Avenue. Thornton's Transportation and Mobility Master Plan (TMMP) [PDF/57.6MB] establishes a goal to provide an interconnected multimodal transportation network accessible to all people. The TMMP identified Huron Street, Pecos Street, and 128th Avenue as short-range priorities for protected bike lanes. Installing protected or separated bike lanes in these three corridors will provide multimodal facilities that are safer, more efficient, easier to navigate and comfortable for bicyclists of all ages and abilities.

The study focused on providing protected or separated bicycle facilities to enhance and connect Thornton's multimodal transportation network. Protected bike facilities provide a physical separation between vehicles and bicycles creating a safer and more comfortable environment for biking. This study will set a precedent for considering other protected bicycle facilities in Thornton. The study was funded through a Transportation Improvement Program grant administered by the Denver Regional Council of Governments (TIP-ID 2022-052).
