Update 4/15/2022 - Due to supply chain issues, construction on the 11th Street Bikeway will now start the end of April (instead of mid-February) and is expected to be completed in October. We apologize for any inconvenience this may cause. 

....

The Ada County Highway District (ACHD) will begin construction mid-April and finish October of 2022. 

ACHD will construct a bikeway that includes a multi-use pathway thru the Boise High School campus, wayfinding and bikeway signage, enhanced crossings, sharrows, and bike lanes. Suez will also be installing a water line down 11th Street between Heron and Fort streets.

What to expect during construction:

  • Lane restrictions
  • Temporary on-street parking impacts 
  • Short-term closures
  • Temporary pedestrian detours
  • Equipment back up alarms and ground vibration
  • General construction noise and dust 

Contractors will coordinate with property owners to maintain access during construction and crews will work between 7 a.m. to 7 p.m., unless otherwise approved. 

Due to contractor staffing issues and supply-chain shortages, construction schedules could change.

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

Highlights 

  • Rehabilitate the pavement on 11th Street between Washington and Heron Streets.
  • Install enhanced pedestrian crossings at Fort/11th, Hays/11th, and Hays/12th with bicycle push buttons and bulb-outs.
  • Construct a new multi-use pathway through the Boise High School campus with all-way stop intersections at Franklin and Washington streets.
  • 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.
  • Install new pedestrian-scale lighting at the bulb outs and multi-use pathway.

Construction is scheduled to begin February 2021 and is expected to be complete August 2021. Utility companies will begin relocating existing overhead and underground facilities prior to the ACHD construction start date.

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.
