A big rig driver lost control of his truck, traveling down an embankment and coming to rest beneath Interstate 805 near National City.
CHP officials declared a SigAlert at 5:58 a.m., temporarily closing ramps from I-805 southbound to State Route 54 in both directions.
The driver was traveling along I-805 southbound when the truck drove off the highway and landed near the base of the overpass without hitting any other vehicles, CHP officials said.
No one was injured.
