Project Overview

This project will reconstruct the 28th Street and Colorado Avenue intersection, adjacent to the campus of the University of Colorado Boulder.

The improvements include redesigning the intersection to include attributes of a protected intersection, as well as new separated bike lanes, a new bus lane, improved vehicle lane connections to 28th/US 36, and ADA improvements.

This intersection was identified for multimodal safety improvements after an extensive engagement process for the 30th and Colorado Corridors Study. The study looked at existing and future travel conditions and needs to identify transportation projects that would improve travel and safety for all modes along the 30th/Colorado corridors.

A public information session will be held in Spring 2022 to share the preliminary designs.

Spring 2022 Update

The 28th Street and Colorado Avenue intersection is undergoing preliminary design based on the recommendation from the 30th and Colorado Corridor Study. A public information session is planned for Spring 2022.

Project Improvements

The improvements will include:   

  • A separated bike lane design known as a protected intersection, which places physical infrastructure between pedestrians / bicyclists and vehicular traffic.  

  • Protected eastbound & westbound bike lanes along Colorado Ave., and realigned bike lanes and crosswalks that are setback behind curb radii at the intersection 

  • New Business Access and Transit (BAT) lanes along Colorado Ave.  

  • A double westbound left turn lane onto 28th St. southbound towards US 36.  

  • Minor improvements including sidewalk improvements, conflict zone pavement marking, and traffic signal improvements 

Project Background

This project was identified for multimodal safety improvements in partnership with CU in the 30th and Colorado Corridors Study. This study looked at existing and future travel conditions and needs to identify transportation projects that would improve travel and safety for all modes in the 30th/Colorado corridors. The study began in 2017 and following community engagement was approved by City Council in 2019. All the projects recommended in the study will help Boulder build out its protected bike lane network for a safer and better-connected bike network around town.

This intersection was initially identified because the street sees a high number of pedestrian, bike, transit, and vehicle activity. This location was among the areas with the highest number of crashes identified in the Safe Streets Report.
