A multi-car crash on northbound I-680 at Sycamore Valley Road in Danville Wednesday left at least one person injured, an SUV on its side and debris scattered across several lanes of traffic.

The California Highway Patrol declared a SigAlert in effect for the 1, 2, and 3 lanes at 3:43 p.m. in order to extricate two people from the upended van or SUV and to remove the wreckage of other vehicles from the roadway.
Traffic is moving – slowly – through the area.
Two at the same time on opposite sides of the highway?
Correct, Kris.
We were right on top of this one but I was too shocked to take pictures!!! Glad the older couple was okay you could see she was really frightened. Surprised there were no serous injuries.
You guys are so fast!! I had this on my mobile as we drove past this wreck..
Pretty hairy!
Missed it by about 5 minutes. Crazy there these days.
