Location 7 (Red Chest)
At the next blockaded area of the road there is a red chest on top of two shipping containers on the left of the road (it is easily visible from the roadway).

Grenade jump from the small boxes east of the chest, or wedge two vehicles against the shipping containers and climb on top of them (which is extremely hard to do). Beware of Lance Pyros, Medics, etc.
