State Route 91/State Route 71 Interchange Improvement Project

RCTC has begun the Project Report and Environmental Document process to improve the connection between State Route 91 and State Route 71 in and near the City of Corona. This project is part of a larger effort to improve mobility along the State Route 91 Corridor in Riverside County and Orange County.

The State Route 91/State Route 71 (SR-91/SR-71) interchange is a significant source of traffic congestion in the area, and this project is designed to reduce this congestion, enhance the safety of motorists, support the movement of goods, and improve mobility and connections between the two freeways and among the counties of Riverside, Orange and San Bernardino. Work on the preliminary engineering and environmental document began in spring 2008 and is expected to take about two years to complete.

This interchange falls within one of four freeway corridors that RCTC has designated as high priorities to receive $2 billion in funding during the next 10 years. These four corridors – SR-91, Interstate 10, Interstate 15, and Interstate 215 – will receive priority funding from Measure A, the half-cent sales tax for transportation improvements in Riverside County. Schedules have been set to fund and deliver major transportation projects along these corridors during the coming decade.
