The Mid County Parkway is a proposed 16-mile transportation corridor designed to relieve east-west traffic congestion in the San Jacinto and Perris areas and help address transportation needs through 2040. A new east-west route is proposed between Interstate 215 and State Route 79.
Why is the Mid County Parkway Needed?
Major transportation routes in southwestern Riverside County are experiencing significant traffic congestion. Traffic volumes near the proposed Mid County Parkway are projected to double in some segments and triple in other segments.
Another east-west transportation link, such as the Mid County Parkway, is essential to reduce traffic congestion and enhance the quality of life for the area. The Mid County Parkway will provide connections to Interstate 215, State Route 79 and multimodal bus and rail facilities that support Metrolink's 91/Perris Valley Line.
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 took action in July 2009 to focus the project limits to the portion between I-215 and SR-79.
In January 2013, RCTC recirculated the Draft EIR/EIS for public review for the refocused project. In January 2014, RCTC recirculated revised sections of the Draft EIR (air quality, greenhouse gases, climate change, and Table 4.10) for public review. In April 2015, RCTC approved the final EIR for the Mid County Parkway. The Federal Highway Administration approved the Record of Decision in August 2015. Following environmental approvals by RCTC and FHWA, RCTC initiated work on the final design of the Mid County Parkway and began to implement the mitigation commitments stipulated in the Final EIR/EIS. In July 2017, RCTC prevailed in court against a CEQA challenge to the project - Click here for more information.
Current Project Status
The Mid County Parkway is in the expenditure plan for Measure A, the voter-approved half-cent sales tax for transportation improvements in Riverside County. Measure A will fund a portion of the project.
Work is under way now for final design of the Interstate 215 Placentia Avenue Interchange, the first of several design packages for the project.
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 is designing a site 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.
