11th Street Bikeway

CCDC and City of Boise, in cooperation with the Ada County Highway District (ACHD) and Idaho Transportation Department (ITD), are designing a bikeway to improve safety and comfort on 11th Street in Downtown Boise. The goal is to create a premier “ridge-to-river” bicycle connection between the Foothills, the Greenbelt, and Downtown Boise

With a direct connection of Camel’s Back Park and the Boise River Greenbelt, 11th Street serves as a priority ridge-to-river bicycle corridor. In addition, 11th Street directly connects residential neighborhoods and downtown business services, entertainment amenities, and employment. Because of this, 11th Street is an essential linkage in the city-wide bicycle network and provides an opportunity for expanded access to downtown.

The City Comprehensive Plan and the City’s Transportation Action Plan recognize the importance of and support better neighborhood connectivity. Support for new bicycle infrastructure that is accessible to all ages and abilities comes not only from City planning, but numerous neighborhood plans, which prioritize a more robust, dedicated bike facility connecting downtown with the foothills and the Boise River. A survey conducted in November 2018 by ACHD found that 92% of respondents supported a bikeway on 11th Street, with many respondents requesting an improved bikeway through downtown

In October 2019, the ACHD Commission unanimously approved the 11th Street Bikeway Concept Plan. This plan recommends bikeway improvements to 11th Street from Heron to State Street. ACHD staff is advancing design of the improvements in preparation for installation in 2022.

Downtown 11th Street Bikeway Concept Design
As ACHD begins preliminary plans for the section of 11th Street north of State Street, CCDC, in partnership with the City of Boise, will study the downtown section of 11th Street from Washington Street to the Boise River Greenbelt over the next eight months. This study area interfaces with the ACHD 11th Street Bikeway project area at Washington Street, and the two areas together cover the full “ridge-to-river” connection on 11th Street.

The Downtown 11th Street Bikeway Concept Design project will:

  • Engage residents, businesses, and street users to understand existing needs and desires along the corridor.
  • Develop a bikeway concept design for 11th Street from River Street to Washington Street that is safe and inviting for all ages and abilities.
  • Provide a plan to connect residential neighborhoods, commuters and recreators to downtown businesses and employment.

Public Process
The first phase of the Downtown 11th Street Bikeway Concept Design began in April 2020 and includes preliminary data collection and analysis by project consultant Kittelson & Associates. The second phase, which included a public survey and mapping tool, began in May 2020 and finished at the end of June. You can view the results from the survey here:

Information and input collected from the project’s first two phases lead to the development of two proposed concepts for the Downtown 11th Street Bikeway Design. CCDC and Kittelson and Associates hosted the project’s first virtual open house on Thursday, September 24. The open house was recorded and is available at 

Results from the second round of outreach is available here: Downtown 11th Bikeway Public Feedback Fact Sheet #2. The project will be presenting the preferred raised bike lane concept design to the CCDC Board of Commissioners and ACHD Commission for consideration in November.

This project page will be updated regularly with opportunities to learn more and provide your feedback as the project progresses. Follow us on Facebook and Twitter pages for updates on this and other CCDC projects.
