Jefferson County Transportation and Engineering held an open house on August 9 at the Columbine High School library to provide information on the South Pierce Street Roadway Improvement design. The county appreciated all the feedback received from the public during the open house. The main concerns Jefferson County received from multiple residents are the following:
The county completed a traffic study with data collected in May 2022 (while school was in session) for the South Pierce Street corridor from West Bowles Avenue to West Coal Mine Avenue. The data included vehicle, bicycle, and pedestrian counts during the a.m. peak hour, school dismissal hour, and p.m. peak hour. The data also observed the U-turn movement at West Polk Avenue / West Caley Place. Below is information about how Jefferson County conducted the analysis and proposed changes:
Jefferson County had an engineering consultant conduct a traffic study along South Pierce Street from West Bowles Avenue to West Coal Mine Avenue in August 2022. The traffic study collected data on existing traffic volumes, level of service provided by the roadway, and recommendations to improve the corridor along South Pierce Street. The county seeks to implement recommendations received from the traffic study. The recommendations included modifications to the existing span wire traffic signal intersections, improvements to the pedestrian and bicycle routes, and modifying access points to the high school.
The project limits are from West Bowles Avenue to West Coal Mine Avenue along South Pierce Street, with improvements to the following intersections:
The project is not a full roadway reconstruction project, but a roadway improvement project with modifications to the existing corridor. These modifications include:
The project will be within the preliminary design phase during the spring of 2023. The county will conduct public meetings to provide information and gather feedback in the Summer of 2023. The final design and bidding of the project for construction will occur in late fall of 2023. Construction of the project is anticipated for spring of 2024.
The impacts to traffic will be fully known as design progresses. At a minimum, the county will require the contractor to keep a single lane of travel in both directions during construction and will work to minimize construction impacts during school traffic hours.
