Rebuild 11th Street Blocks
Construction Status as of September 15th
RIVER STREET TO IDAHO STREET
Work on 11th Street between Front St and Mrytle St will switch to the west side of the road starting Monday, September 18. Over the next three weeks, crews will demo, install underground utilities and reconstruct the NW corner of Myrtle St and the SW corner of Front St. Roadway concrete pours continue between Main St and Idaho St. Crews are also working between River St and Lee St to complete alley work and the streetscape improvements on the west side of 11th St.
Vehicle Access
- During this phase of construction there will be a full street closure on 11th St from Main St to Idaho St.
- Southbound travel on 11th St between Myrtle St and Front St will be reduced to one travel lane.
Bicycle and Pedestrian Detour
- Pedestrian detours will be changing frequently due to the nature of the work occurring. Please follow the detour signs in place and pay close attention to your surroundings.
- Cyclists will be detoured to 15th and 16th Streets.
From concepts to creation, Capital City Development Corp. (CCDC) is fulfilling our community’s expressed desire for an 11th Street that is safer and more convenient for all users to access restaurants, entertainment, and open spaces.
CCDC is undertaking several large-scale projects originating from a multi-year planning effort between Ada County Highway District (ACHD), the City of Boise, and CCDC. By taking a coordinated approach to what would be multiple projects, Rebuild 11th Street reduces disruption to downtown daily life and minimizes delays.
This project will complete necessary and anticipated roadway reconstruction and replace underground Boise City Canal structures dating back to the 1950s on behalf of ACHD and the Canal District. It makes long-envisioned bicycle improvements with an all-ages, all-abilities protected bikeway from State Street to River Street and improves streetscapes where needed to support economic vitality and increase connectivity in our downtown.
A number of notable projects are located along or adjacent to 11th Street, including the new Cherie Buckner-Webb Park, the upcoming Block 68 Catalytic Development Project on State Street, and improvements to the Linen Blocks on Grove Street.

Frequently Asked Project Questions
The goal for this project is to make planned improvements to the street, sidewalks, and intersections that provide safer, less congested travel options, a more comfortable experience, and expanded access to businesses whether arriving by foot, bicycle, or vehicle.
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
ACHD anticipates construction to begin end of April and finish October of 2022.
Yes! Throughout the phases of construction, the project team will ensure that businesses are accessible with ample detour signage and construction safety barriers. Additionally, the team will work to limit noise, dust and disruption as much as possible during business hours.
Streetscapes refer to the design of our urban public right-of-ways including sidewalks, streets and crossings. This project will make improvements such as increased lighting and street trees, added furnishings like bike racks, planters, and trash receptacles, and expanded sidewalks. All these enhancements create an attractive and inviting neighborhood and can help spur local economic activity.
An important component of Rebuild 11th Street Blocks are strategic changes to high-use intersections in order to reduce conflicts between pedestrians, cyclists and motor vehicles.
These treatments include raised median islands at Myrtle Street and Front Street that provide physical protection for pedestrians and cyclists while beginning to cross and slows the speed of turning motor vehicle traffic. The intersections of 11th and Myrtle, 11th and Front, and 11th and State Street also will receive signal adjustments by ACHD to provide a Leading Bicycle/Pedestrian Interval (LBI/LPI), which allows walkers and bikers to start crossing before the motor vehicle green light, increasing their visibility and decreasing the risk of conflicts with turning vehicles.
All intersections will have green “ladder striping” on the roadway, similar to a pedestrian crosswalk but for bikes, which provides a high visibility path for cyclists through the intersection. Pedestrian ramps are being realigned and brought into ADA compliance where needed. The 11th and Grove Street intersection will have expanded curb and sidewalk areas called “bulb-outs”, which reduces the crossing distance and exposure for people walking and biking, and helps slow motor vehicle speeds.
