A significant traffic collision occurred today on the southbound on-ramp to State Route 73 (SR-73) at Macarthur Boulevard in Newport Beach, CA, leading to major traffic disruptions. The incident involved two vehicles, including a gray Mercedes van, which was confirmed to be drivable after the collision. One vehicle was towed from the scene.

Emergency services responded promptly with multiple units to manage traffic diversion and ensure scene control, directing vehicles off the main roadway to alleviate the backup.
