OVERVIEW

The Riverside County Transportation Commission (RCTC) is conducting safety and road improvements along a major 8.6-mile segment in the County of Riverside. Major roadway improvements will be made along the Ramona Expressway from Warren Road to about one mile east of Rider Street in the County. This segment is within the Mid County Parkway, also known as the MCP, a planned 16-mile corridor between Route 79 in the Hemet Valley and Interstate 215 in Perris. Construction is set to take place from early 2026 to 2028.

The MCP Ramona Expressway experiences a high rate of vehicular collisions. To address the high priority safety and access needs in the area, RCTC has deferred final design of the MCP Segment #1, west of Ramona Expressway. Roadway improvements along Ramona Expressway will include the following:

  • An additional travel lane in each direction (one to two lanes)
  • A raised median
  • Construction of a new bridge over the San Jacinto River
  • Traffic signal upgrades
  • Construction of a wildlife crossing

These upgrades are designed to improve motorist safety, reduce travel times, and expand access to jobs, education, and transit. The Ramona Expressway serves as a vital link that provides equitable access to multiple modes of travel with connections to SR-79, I-215, and transit facilities that support Metrolinkโ€™s 91/Perris Valley Line and Riverside Transit Agency routes.

During construction, periodic lane closures and traffic shifts are expected. Work may take place during daytime, nighttime, and weekends hours. Motorists should plan for extra travel time. Access to homes and businesses will be maintained where possible. Construction alerts will be posted as updates are made available. To receive alerts via email, sign up using the form below.

Project Status

Final design of the 8.6-mile segment on Ramona Expressway is complete, and construction is set to begin in early 2026 for approximately two years.

RCTC also is working to fulfill its environmental mitigation commitments:

Under the Multi-Species Habitat Conservation Plan, RCTC has acquired more than 177 acres of land to mitigate project impacts to sensitive plants and wildlife.

  • RCTC has created a wetland area to mitigate impacts to aquatic resources in order to obtain a permit from the U.S. Army Corps of Engineers.
  • RCTC also is preparing a Cultural Landscape Study to mitigate project impacts to historic properties.
  • RCTC deferred final design of a previously identified segment from Redlands Avenue north of Placentia Avenue that would have continued east and connected with Ramona Expressway south of Lake Perris, in order to address the high priority safety and access needs along the Ramona Expressway segment.

MCP RAMONA DSCN4254

Location: Western Riverside County

Status: Pre-Construction

Type of Project: Expressway

Location: Western Riverside County between San Jacinto and Perris

Type of Project: Highways

Fact Sheet

OVERVIEW

The Mid County Parkway (MCP) Alignment is a long-term transportation improvement initiative led by the Riverside County Transportation Commission (RCTC) to deliver a planned 16-mile eastโ€“west transportation corridor between western San Jacinto and eastern Perris. The program is designed to reduce travel times, improve and update roadway safety components along the entire corridor, and open new economic opportunities by expanding access to employment, education, and regional destinations for residents and businesses in central Riverside County. These improvements promote transportation equity in a long-underserved area while supporting future growth and mobility needs.ย 

The MCP Program is made up of five projects, each advancing independently based on funding availability, regional priorities, and safety urgencies.ย 

  • Future MCP Segment โ€“ Deferred in favor of the Ramona Expressway Segmentย 
  • Future MCP Segment โ€“ Connects to SR-79 in San Jacintoย 

Together, these projects will implement comprehensive safety improvements across the entire alignment, addressing documented collision history and improving roadway safety for pedestrians, motorists, freight operators, bicyclists, and community members. When complete, the MCP Alignment will connect State Route 79 to Interstate 215 and key transit facilities supporting Metrolinkโ€™s 91/Perris Valley Line and Riverside Transit Agency routes, creating a safer, more reliable, and more integrated multimodal transportation network for Perris, San Jacinto, and multiple unincorporated Riverside County communities in the area.ย

Interstate 15 Smart Freeway Pilot Project

Under Construction

15 Smart Freeway Project Map

Status: Under Construction

Location: Western Riverside County

Type of Project: Highways

Location: Northbound Interstate 15 from the San Diego/Riverside County Line in Temecula to the 15/215 Interchange in Murrieta

Engineering/Environmental Studies: Completed late 2023

Construction: Winter 2025 to Fall 2025

Investment: $33.5 million

Fact SheetSmart Room

OVERVIEW

RCTC, in partnership with Caltrans, the City of Temecula, Western Riverside County Council of Governments (WRCOG) are implementing an innovative corridor approach for improved traffic operations on northbound I-15 from the San Diego/Riverside County Line in Temecula to the I-15/I-215 Interchange in Murrieta.

The pilot project will use sensors and “smart” technology to continuously monitor real-time traffic conditions on this eight-mile, non-tolled section of I-15. Severe traffic congestion occurs in this area, due to a high volume of vehicles entering the freeway simultaneously, especially during peak afternoon and evening hours. The pilot project will also use ramp meters that work as a coordinated system that adapts to allow more or fewer vehicles to enter I-15 at any given time from the Temecula Parkway, Rancho California Road, and Winchester Road on-ramps.

Designed as a two-year pilot project, the project is anticipated to improve overall traffic flow and reduce rear-end collisions by maintaining steady travel speeds within the I-15 corridor, without highway expansion and related construction costs and impacts.

Drivers may initially experience short delays on the on-ramps but will gain overall time savings once on the freeway, with fewer stops and starts.

Project Status

RCTC began construction in January 2025.

Construction Updates

Project Schedule

Construction, including installing the โ€smartโ€ technology, coordinating the on-ramp signal timing, and placing roadside informational signs, began January 2025 and should take about a year. Operations may start in 2026 and will continue as a pilot project for two years.

During the pilot period, RCTC and Caltrans will evaluate the project to assess its effect on traffic congestion and determine possible expansion of the program statewide. This schedule is subject to change.

Project History

  • 2019 โ€“ RCTC began exploring smart freeway technologies
  • March 2022 – RCTC received $5 million of Community Project Funding in the federal Appropriations Omnibus Bill, through the support of Congressman Ken Calvert. The $5 million allocation will complete the $18 million funding package for the I-15 Smart Freeway Pilot Project.
  • 2023-2024 โ€“ Completion of engineering and environmental studies and final design; release of construction bid
  • January 2025 – Construction begins on the project.
