11th Street Bikeway

Review the story map of the 11th Street project here!

The Ada County Highway District (ACHD) started construction mid-April and is anticipated to finish November of 2022.

ACHD is constructing 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.

Project Description

The Ada County Highway District (ACHD) 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.

Commuters are reminded to obey all road closure signs and follow the signs along the detour route. Commuters should never attempt to drive, bike, or walk on closed portions of the road, regardless of whether there appears to be active construction. It is unlawful to move or manipulate construction signs and doing so can put commuters and construction workers at great risk.
