Cassia Street Bikeway & Sidewalk Projects


Summer 2020 Update 

Thank you to all that attended the January 2020 open house. If you are interested in what we heard from attendees, please check out the comment summary here.

We are currently finalizing design of the project and are scheduled to begin construction around January 2021. The construction effort that will take place over the winter will primarily consist of any work involving irrigation canals and facilities. Construction activities such as sidewalk installation, pedestrian signal installation, and roadway paving will take place in the spring/summer 2021. We will be providing additional updates as we get closer to construction.


 We always value your comments, but the comment period ended on January 23, 2020.

Join us to learn about bike and pedestrian improvements for Cassia Street!

The Ada County Highway District (ACHD) has been working with the community to develop a bikeway design for Cassia St. from Kootenai St. to Franklin Rd. since 2018.

The design includes bike lanes, signalized pedestrian/bicycle crossings, a new pedestrian bridge at Cassia Park, a raised intersection, and more.

In addition to the bikeway, sidewalks are being designed for Cassia Street, between Latah and Shoshone, and Cassia between Troxel and Franklin Park where they currently don't exist.

*The proposed bikeway includes streets beyond Cassia Street. Please check the route map to see which streets are included in the bikeway.*

The Cassia & Shoshone Bikeway Projects were adopted by the ACHD Commissioners on Wednesday, October 24, 2018.

General Description:
The Ada County Highway District (ACHD) is beginning the design of the Cassia Street Bikeway. The goal of the project is to prepare a concept design for a bikeway that will be comfortable for people of a wide range of ages and abilities to bike on.

*Please note that the proposed bikeways include streets beyond Cassia Street. Please check the proposed route maps to see which streets may be included in each bikeway.

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.

Why Cassia Street?

Cassia Street was identified as a potential bikeway in the 2012 Boise Central Bench Neighborhood Pedestrian and Bicycle Plan. It's also included in the 2018 Roadways to Bikeways Bicycle Master Plan Update.
