Mineral Mobility Improvements

Improvements will be constructed in phases as funding is secured. Detailed descriptions of the phase 1 elements have been completed and are listed below and are identified on the image below by the yellow notes. Construction of phase 1 will begin in early 2025 and completed by the summer 2025. Design of the phase 2 elements, generally described below and represented by the purple notes on the image, will be finalized in 2025. Construction of phase 2 is anticipated to begin in late 2025 and completed in 2026.

• Jackass Hill Road – Enhance the existing bike lanes to be buffered on each side of the street (to be converted to protected bike lanes in the future once maintenance of the bike lanes can be resolved).
• Jackass Hill Road & Jamison Way/Curtice Court Intersection – Intersection modifications to reduce vehicle speeds, to provide protection for bicyclists from turning vehicles, and to clearly direct pedestrians and shorten crossing distances.
• High Line Canal Trail Extension Crossing of Jackass Hill Road – Crossing modifications to reduce vehicle speeds through the curve, along with a pedestrian activated Rectangular Rapid Flashing Beacon, where lights flash both at the crossing and in advance of the crossing for northbound traffic to alert drivers of the presence of a pedestrian or bicyclist.
• Mineral Avenue Trail East of Jackass Hill Road – Paved trail with designated space to separate bicyclists and pedestrians.
• Mineral Avenue Roadway– Enhance the existing bike lanes to be buffered on each side of the street (to be converted to protected bike lanes in the future once maintenance of the bike lanes can be resolved) from Jackass Hill Road to Windermere Street, and encourage bicyclists out of the roadway onto the shared use path west of Jackass Hill Road.
• High Line Canal Trail Crossing of Mineral Avenue – Improved bicycle and pedestrian crossing with better visibility for vehicles on Mineral Avenue, more clearly defined crossing for trail users, and upgraded facility equipment. (The city continues to pursue funding opportunities for an underpass as the ultimate vision.)
• A second phase (shown in purple on the map) will provide improvements to the Mineral Avenue & Jackass Hill Road/Long Avenue intersection to add physical and signal timing separation for bicyclists and pedestrians, as well as widening the sidewalk on the north side of Mineral Avenue between Jackass Hill Road and the bridge to RTD’s Mineral Light Rail Station. The emergency repair of the culvert at Jackass Hill Road just north of Mineral Avenue will integrate into the planned intersection improvements in this second phase of the project.

December 2021/January 2022 Online Engagement

Comments regarding existing transportation concerns and desired improvements in the area were accepted via a survey and comment map between December 17, 2021 and January 7, 2022. The summary available through the link below outlines the outreach conducted and lists comments received. The input received was used by the city to develop a list of improvements to be considered.

Give feedback regarding the preliminary (30%) design that will be used to optimize improvements as the design is finalized (may be held virtually).

In addition to this project, there are two additional projects occurring within the larger study area. Learn more about the projects and provide your input by following the project name links below.

Santa Fe Planning and Environmental Linkages (PEL) Study: This study will identify future transportation and safety improvements for an 11-mile stretch of Santa Fe Drive between C-470 and Alameda Avenue.

Santa Fe & Mineral Improvements Project: This project aims to reduce congestion and improve safety at the Santa Fe Drive and Mineral Avenue intersection by constructing a new roadway in the southwest quadrant of the intersection. The quadrant road concept will remove left turning movements from the intersection to prioritize east-west and north-south travel.
