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.*

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.
