Martin Kueth Bol Gatdor is the headmaster of the Comboni school in Old Fangak, South Sudan. He wanted a way to help his students cross a washed-out road on their way to class. He took the project on alone, and began by building supports for a handmade bridge. Soon, his students rallied to the cause, gathering material and helping with construction. Now the whole school is enjoying the benefits of this ingenious effort.
