The projected growth and development forecasts indicate that traffic volumes will continue to increase along the corridor. Traditional Federal and State funds are not sufficient to provide this needed congestion relief, therefore tolled express lanes are considered to be the most feasible solution. Tolled express lanes are proven to offer time savings in all lanes, and provide an alternative choice for commuters traveling through an area with prolonged traffic congestion during peak hour travel times.  Additionally, tolled express lanes are designed to improve travel time reliability, improve operational performance, promote ridesharing, and reduce pollution in the region. The Riverside County Transportation Commission, in cooperation with the California Department of Transportation District 8, is proposing this project to improve traffic flow and reduce congestion on this portion of the Interstate 15. All proposed improvements are anticipated to be constructed within the existing right of way, with the majority of the improvements occurring within the existing I-15 median.
