Temescal Canyon Road Improvement Project

Project Overview

To improve traffic flow along the Temescal Canyon corridor, the County of Riverside proposes to widen three segments of Temescal Canyon Road from one lane in each direction to two lanes in each direction. 


The proposed improvements will remove the existing roadway and construct a full widened street, install storm drain improvements, relocate power poles, tie in driveways, construct curbs, and construct sidewalk on one or both sides of the street.

Specifically, the new street improvements will provide two 12-foot lanes and an 8-foot bike lane (with no on-street parking) in each direction, along with a center 12-foot two-way left turn lane.  In addition, 6-foot wide curb adjacent sidewalk will be constructed on one or both sides of the street.
