The Mid County Parkway is a proposed 16-mile transportation corridor that will relieve traffic congestion for east- west travel in western Riverside County between the San Jacinto and Perris areas and help address future transportation needs through 2040.

The Riverside County Transportation Commission (RCTC), the agency responsible for transportation in Riverside County and the administrator of Measure A (Riverside County's 1/2 cent sales tax for transportation), has completed the environmental studies for the modified alternatives for the Project.


PRESS RELEASE FOR Mid County Parkway CEQA Challenge new

The Final EIR/EIS was prepared and finalized with concurrence from all the agencies (FHWA, Caltrans, USACE, USFWS, USEPA, and CDFW) involved in the MCP project in 2015. new

On August 17, 2015, FHWA as the lead agengy under NEPA approved the Record of Decision (ROD) for the MCP Project. The Final EIR/EIS and ROD are available electronically on this website under "Library/Links." new

Now that the Record of Decision (ROD) is approved, the project can begin the Right of Way Acquisition and Plans, Specification & Estimates (PS&E) Phases. new

Since the approval of the MCP EIR/EIS and Record of Decision, a great deal of progress has been made to advance the project to design and construction.

  • For design, a contract was awarded November 2016 for the I-215/Placentia Interchange, the first of several design packages that will be needed to complete the project.
  • For environmental compliance, we have made signifigant progress in fullfilling our mitigation commitments under the MSHCP, which must be fully completed before construction can start. Work is also underway to meet requirements for an Army Corps 404 permit needed for construction and work is underway for the Cultural Landscape Study.


There are currently legal challenges to the environmental approvals of the project, which are making their way through the courts. In the meantime, the commision is proceeding with final design for the first construction contract, which consists of the I-215/Placentia Interchange. The Commission is currently acquiring right-of-way for this protion of the MCP only. RCTC continues to move forward with meeting the environmental mitigation requirements and neccessary permits for construction.

The project is in the expenditure plan for Measure A, Riverside County's 1/2 cent sales tax measure for transportation, which will fund a portion of the project. new
