Key 2: Immediately after the tollbooth there is another car hanging off of the edge to the left. The key is poking out of the back.
Key 3: Immediately to the right upon entering the covered area just past the tollbooth should be a school bus. The key is in the left door of the car on top of the bus.
Key 4: Down the bridge, after the containers that form a small crossing, there's a car suspended over the middle of the platform above you. There is a key in the back.
