The Ada County Highway District (ACHD) is currently designing bikeway improvements for 11th Street to create a continuous connection from the North End and Camel's Back Park to Downtown Boise.

  • Rehabilitating the pavement on 11th Street between Washington and Heron Streets.
  • Enhanced pedestrian crossings that include shortened crossing distances and rectangular rapid flashing beacons at key intersections. One of the key intersections is now 12th and Hays. It was included based on earlier public feedback.
  • A new multi-use pathway through the Boise High School campus.
  • A phased approach near Washington Street which will start with painted sharrows (a lane marking that indicates vehicles and cyclists share the road). A future phase may add full bicycle lanes which will remove parking along this section (approximately 10 spaces). This will be determined after coordination with the YMCA and City of Boise.
  • New pedestrian-scale lighting at the bulb outs and multi-use pathway.

Construction is scheduled for the summer of 2022.

The 11th Street Bikeway was adopted by the ACHD Commission on October 23, 2019.

Highlights of the plan include enhanced pedestrian crossings, bulb outs, and a multi-use pathway through the Boise High School Campus. In addition, the plan proposes a two-phased approach to removing on-street parking and adding bike lanes on the section of 11th Street between Washington Street and State Street.


In late 2018 the Ada County Highway District (ACHD) asked the community to participate in an online survey to help us start planning a bikeway for 11th Street. If you provided feedback - thank you!

Based on public input we have developed a proposed bikeway design and want to know what you think. Join us on July 11th to learn more and give us your feedback.

Thank you for your interest in the bikeway. The survey closed on July 25, 2019.


The Ada County Highway District (ACHD) is beginning design of the 11th Street Bikeway, between Heron Street and State Street. The goal of the project is to prepare a concept design for a bikeway that will be comfortable for a wide range of ages and abilities to bike on.

Why 11th Street? 11th Street was identified as a potential bikeway in the 2016 North Boise Neighborhood Pedestrian and Bicycle Plan. It's also included in the 2018 Roadways to Bikeways Bicycle Master Plan Update.

What is a bikeway? A bikeway is a route, way, or path that is specifically designed and/or designated for bicycle travel. A bikeway does not preclude vehicular travel but enhances the roadway character and experience for cyclists.
