This multi-phase corridor analysis evaluated alternative alignments of a 32-mile east-west limited access route in western Riverside County to relieve congestion, improve safety and help address future traffic demands. The overall project included analysis of freeways, three system interchanges, 16 service interchanges, and connecting local streets.  Originally identified during the Riverside County Integrated Project (RCIP), the Mid County Parkway was proposed to extend from SR-79 near San Jacinto to I-15 near Corona, running parallel to Cajalco Road and Ramona Expressway.  Based on public comments and other factors, the project was later modified to extend from SR-79 near San Jacinto to I-215 near Perris.

VRPA led all noise and traffic analysis associated with the project, including the incorporation and update of local jurisdiction socioeconomic data and road networks for the travel demand modeling and traffic analysis for seven (7) alternatives. This effort included coordination between five (5) Cities and the County of Riverside.  The Southern California Association of Governments (SCAG) Regional Transportation Model and the Riverside Traffic Analysis Model (RivTAM) were utilized for the project. VRPA led efforts to compare and analyze the existing 2030 socioeconomic files against local City General Plans and new development projects surrounding the project area.  

As part of this project, VRPA prepared a signing plan for the I-15 freeway with the project in place.  It included the location and layout of all major freeway guide signs.
