Dashrath Manjhi was born in to the lowest rung of India’s caste system in Gehlaur village, India, and ended up working in coal mines. When he was an adult, his wife was injured and died because the nearest doctor was in a town 34 miles away.
Because of this experience, Manjhi decided that he was going to make a new roadway through a ridge of hills, in order to make his village more accessible. Manjhi ended up carving a 110m long path, completing it in 22 years (between 1960 and 1982), using only a hammer and a chisel.
Ultimately, Manjhi’s road reduced the distance between the start and finish areas from 34 miles to 9.3 miles.
