The I-215 Placentia Avenue Interchange is the first construction project of the Mid County Parkway, a new 16-mile transportation corridor between the San Jacinto and Perris valleys. The Mid County Parkway is designed to reduce travel times between these areas. Please see the Mid County Parkway page for details about this corridor.

Designed to meet the needs of a growing population, the project will add a new interchange to I-215 at Placentia Avenue, between Ramona Expressway to the north and Nuevo Road to the south. The new interchange will improve access, traffic flow, and air quality by adding on-ramps and off-ramps to Placentia Avenue, realigning East Frontage Road, widening the Placentia Avenue overcrossing, and adding lanes to Placentia Avenue between Harvill Avenue and Indian Avenue.

Construction begun on August 24, 2020 and the interchange is expected to open by summer 2022.
