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 & Public Process
CCDC, in partnership with the City of Boise, completed a concept development process that engaged with residents, business and property owners, and street users to understand existing needs and desires along the corridor and the outcome was a bikeway concept for 11th Street from State Street to River Street that is inviting for all ages and abilities. The project team evaluated multiple alternatives to meet the project’s goal of providing a low-stress bicycling experience to a range of people and to respond to feedback heard during the two public outreach efforts. Feedback from the public and stakeholder agencies resulted in the recommended raised bike lane design for the Downtown 11th Street Bikeway. It will provide physical separation from motor vehicles and easier access for bicyclists to bicycle parking and businesses along the street. The design maintains on-street parking on both sides of the street. The recommended design also includes treatments that will improve safety and comfort at the intersections. This downtown segment of the 11th Street Bikeway spans two Urban Renewal Districts (River-Myrtle / Old Boise and Westside) both of which have funding programmed in FY2022 to build the infrastructure associated with this bikeway as well as streetscape improvements. This project 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.
