The California Highway Patrol shut down a rave that popped up under a South Bay freeway early Sunday morning.
The "ramp rave" took place underneath Interstate 5 near Main Street in the Palm City neighborhood of San Diego. Authorities were alerted to the event around 1:30 a.m. on Sunday.
Video from the scene shows a sophisticated party setup with lights, a stage, stereo equipment and generators to run it all. Bottles of water and liquor were also found at the scene, the footage shows.
In September, NBC 7 cameras were rolling when San Diego police ended a rave under the Morena Boulevard overpass. The station covered another rave under the 805 overpass in Sorrento Valley in July.
