A traffic collision on Interstate 805 South (I-805 S) in San Diego, CA, caused significant disruptions to traffic flow today. The incident occurred around 12:30 AM, involving three vehicles: a FedEx semi truck, a Mack Anthem truck, and a big rig with a 50-foot trailer. The FedEx truck collided with a concrete barrier, prompting an emergency response.

Emergency units quickly arrived at the scene to manage traffic and ensure safety. As a result of the collision, multiple lanes were closed, leading to delays and congestion for motorists traveling along the I-805 S and State Route 163 South (SR-163 S) corridor. The lane closures created backups, affecting the morning commute for many drivers.

The FedEx truck remained on site pending towing, while the Mack Anthem truck was documented for towing details. The big rig trailer was also noted, but its load status was unclear. Emergency responders worked diligently to control the scene and facilitate traffic management.

Motorists were advised to seek alternate routes to avoid the area until the situation was resolved. This traffic incident underscores the importance of safe driving practices, particularly during late-night hours when visibility may be reduced.
