71/91 Interchange Project

Status: Pre-Construction

Location: Western Riverside County

Type of Project: Highways

Location: 71/91 Interchange

Construction: Anticipated from 2022 to 2024

Investment: Estimated $118 Million


The Riverside County Transportation Commission, in partnership with Caltrans, has received project approvals and has completed final design for the 71/91 Interchange Project in Corona. RCTC is actively seeking funding to improve this congested and operationally deficient interchange.

Caltrans approved the environmental document in June 2011, and RCTC completed final design for the project in June 2015. RCTC is actively seeking funding to build the estimated $118 million project. Funding could include federal, state and local sources.

Once RCTC receives funding, construction could begin in early 2022 and be completed in about three years. Construction likely would occur in stages to minimize disruption to motorists through this heavily traveled corridor.
