Local Context

The westbound 91 Fwy at La Sierra Ave is a heavily traveled interchange in Riverside, providing access to residential neighborhoods and major retail centers near La Sierra Ave and Magnolia Ave. The off-ramp and on-ramp configuration in this area often involves merging traffic and vehicles slowing to exit the freeway. Late-night traffic can still move at freeway speeds, increasing the risk of serious crashes when a vehicle loses control near ramp transitions. Responders working along the 91 Fwy must coordinate closely to manage traffic flow and ensure safety while assisting injured parties on or near active lanes.
