Project scope is to reconfigure the 71/91 Interchange in west Corona, with the goal of expanding the passage to accommodate more vehicles and lessen the likelihood of accidents.  The project is another example of RCTC’s efforts to improve mobility along one of our most congested areas countywide.

Specifically,  project scope will entail replacing the current single-lane connector from the eastbound 91 to the Corona (71) Expressway with a two-lane connector loop, which will facilitate a larger volume of vehicles at one time, reducing congestion.  The project will further add an eastbound 91 auxiliary lane next to the highway shoulder and realign the eastbound 91 Green River Road on-ramp to the south. The project will also will slightly realign southbound 71 to create space for the new connector.

Once completed, the new interchange will improve safety, with reduced weaving between lanes and rear-end collisions, expand access to other modes of travel, such as Metrolink trains, and enhance traffic flow by replacing the single-lane loop with the two-lane direct connector.
