Project Overview

The North Broadway Reconstruction Project provides long-term pavement maintenance and improves safety and comfort for people using all modes of travel through this section of roadway from Violet Avenue to US 36.


Project planning and design happened from 2016 to 2020. Construction began in spring 2021 and ended in spring 2023. While not part of this project, Xcel Energy converted existing overhead distribution lines to new underground distribution lines alongside North Broadway. Find details on the Xcel Energy project webpage.

Project Updates

Additions in spring 2023 include:

  • The underpass and multi-use path opening for everyone to walk, bike and roll.
  • Completing final striping of the bicycle lane.
  • Prohibiting overnight parking to allow for an improved snow and ice response.
  • Stepping up parking enforcement to ensure that people are parking as close to the curb as possible.
  • Posting additional parking signage to educate drivers that this is shared space.
  • Completing the southbound raised bike lane from Yarmouth to Violet avenues, which had been paused due to winter conditions and resource constraints.

The project construction, including these measures, ended in 2023.

Project Design

While the North Broadway Reconstruction project’s primary goal is to provide long-term pavement maintenance, safe, low-stress travel options are a key consideration and the city incorporates multimodal improvements into transportation projects whenever possible.

Community engagement on this project reflected a strong desire for a multi-use path for all ages and abilities. Although protected bike lanes were also considered, the final raised, buffered bike lane design ensures that the project has space for this multi-use path on the west side while also balancing the trade-offs associated with limited roadway space.

This design aligns with the North Boulder Subcommunity Plan and the Low-Stress Walk and Bike Network to support infrastructure for safe and comfortable transportation options across the city.

Scope of Improvements

The roadway pavement on North Broadway is in poor condition and requires reconstruction. This project will provide a more durable pavement that does not require as frequent maintenance and provide a safer and better riding experience for drivers, transit riders and on-street bicyclists.

The project applied for and received a federal grant to reconstruct the pavement in concrete as well as retain and possibly enhance or add pedestrian, bicycle and transit stop facilities and improvements. There is also some funding for street lighting, landscaping and public art.

The updated scope includes:

  • Pavement reconstruction in concrete and new curb and gutter
  • Improvement to the on-street bicycle facilities
  • Multi-use path on the west side of Broadway from Violet Avenue to US 36
  • Installation of a traffic signal at Broadway and Yarmouth Avenue and new or improved traffic signal interconnection and bicycle detection systems
  • Pedestrian and transit stop upgrades
  • Construction of a new drainageway underpass for the Fourmile Canyon Creek crossing of Broadway
  • Reduction of posted speed limits from 35 mph to 30 mph from Violet Ave to south of Lee Hill Drive and from 40 mph to 35 mph from south of Lee Hill Drive to US 36.


The state funding is $6.2 million with a local City of Boulder match of $1.3 million. The remaining required funds will come from the city.

This supports the budgeting principles and priorities of the Transportation Master Plan, which makes preserving the existing transportation infrastructure and system a high priority.

Community Engagement

2020 Open House

An open house to present the final design, construction timeline and anticipated impacts was held in early 2020.

June 2019 Open House

Please note that the materials provided below do not include the raised, buffered bike lanes recommended at the Transportation Advisory Board meeting on Aug. 13, 2019.

In August 2019, TAB voted to support the updated recommended design for the project, which includes raised/buffered bike lanes on Broadway from Violet Avenue - Lee Hill Drive, buffered bike lanes from Lee Hill Drive to US 36 and an off-street multiuse path along the west side of Broadway.
