Deputies were responding to the scene as of 10 p.m. Wednesday. The sheriff's office did not immediately release details about the number of vehicles involved, the severity of the injuries, or what caused the collision.

Motorists are being urged to avoid the area and use alternative routes while investigators work. The closure affects a stretch of Cassat Avenue, a key north-south corridor on the city's west side, and could disrupt evening travel for nearby residents and commuters.
