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 Metrolink’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.

Project Schedule

Construction is expected to take place between early 2026 and 2028.

Project History

  • July 2009: In response to comments received from the public on the Draft Environmental Impact Report/Environmental Impact Statement (EIR/EIS) for the proposed original Mid County Parkway between Interstate 15 and State Route 79, RCTC takes action to focus the project limits on the portion between I-215 and Route 79.
  • January 2013: RCTC recirculates the Draft EIR/EIS for public review for the refocused project.
  • January 2014: RCTC recirculates revised sections of the Draft EIR (air quality, greenhouse gases, climate change, and Table 4.10) for public review.
  • April 2015: RCTC approves the final EIR for the Mid County Parkway.
  • August 2015: The Federal Highway Administration approves the Record of Decision. Following environmental approvals by RCTC and FHWA, RCTC initiates work on the final design of the Mid County Parkway and begins to implement the mitigation commitments stipulated in the Final EIR/EIS.
  • November 2016: RCTC awards a design contract for the I-215 Placentia Avenue Interchange.
  • July 2017: RCTC prevails in court against a CEQA challenge to the project
  • July 2018: RCTC resolves litigation for project
  • August 2020: Construction starts on the I-215 Placentia Avenue Interchange in Perris, the first MCP segment.
  • June 2022: RCTC defers work on 3-mile segment near Redlands Avenue in Perris in favor of an 8.6-mile segment along Ramona Expressway, due to high priority safety needs on Ramona Expressway.
  • Fall 2022: Final design begins on Ramona Expressway segment.
  • Fall 2022: I-215 Placentia Avenue Interchange opened.
