Overview
The California Avenue Community Livability Project was implemented to increase livability, safety, and mobility for all roadway users. The project transformed California Ave from Redwood Rd to 700 West from a four-lane undivided roadway into a complete street with one vehicle travel lane in each direction, a continuous two-way left-turn lane and bicycle lanes. The project was constructed in August 2011.
Traffic volume and speed data
When traffic volumes are within a certain range, converting a road from four lanes to three generally has little impact on how much traffic it carries. Traffic on 1300 South fell within this range, so we expected minimal change. This type of conversion often lowers travel speeds, as drivers must follow the pace of the lead vehicle without an extra lane to pass slower traffic.
