Project Overview

The County of Riverside Transportation Department (County) proposes to widen and restripe Ontario Avenue from State Street to Diplomat Avenue to provide a four-travel lane facility consisting of two southbound lanes, two northbound lanes, one two-way left-turn lane, and two marked on-street bike lanes. The roadway is currently striped for a three-lane configuration with two southbound lanes, one northbound lane, one two-way left-turn lane, and no bike lanes. The project would entail resurfacing the existing roadway and widening along the east side between Diplomat Avenue and Rising Sun Road for a consistent 64-feet-wide curb-to-curb width. Other project improvements include the conversion of existing drainage inlets to catch basins and completing a missing sidewalk segment along the west side of Ontario Avenue between State Street and Piute Creek Road.
