The crash happened around 8:45 a.m. on Macalla Road, and SKY7 video showed the cherry picker that had fallen off a flatbed truck, blocking a significant portion of the road.
The incident led police to close the offramps from the Bay Bridge to Yerba Buena Island.
Traffic backed up on the bridge, though the disruption to the commute appeared to be minimal.
It was not immediately clear when the offramps would reopen. Caltrans is working to clear the crash scene.
