Oval UFO over the 14 freeway that floated above the freeway

On August the 6th at around 9:15/9:30pm on the 14 freeway (CA) going towards Santa Clarita, from Acton (around the more mountainous area) I saw what I first thought was a blue shooting star. As we drove closer (finance was driving) I saw that it wasn't a streak of light but a bunch of blue lights (some small some big, but all in a row). As we drove closer, the lights and the out line of the ship around it became more clear. It was a long rice grain shape with the blue lights in the center of it looking almost like windows (?) it also was about the size of a football field. It was hovering above the desert/cliffy area on a slant (it was in it was not straight it was at a 45 degree angle) on the right hand of the freeway. I kept staring at it panicking and sticking my head out the widow to get a better look. It moved and hovered over the freeway and and within seconds the lights turned off in a row and it completely vanished. I know others saw it, as i looked at the truck behind us and saw the truck driver sticking his phone out the window towards the sky and other people in cars sticking there heads out the window. The freeway wasn't in traffic but was densely populated.
