He completed the work in 22 years (1966–1983). This path reduced the distance between the Atri and Wazirganj sectors of the Gaya district from 55 km to 15 km. Though mocked for his efforts, Manji's work has made life easier for people of the Gehlour village. Later, Manjhi said, "Though most villagers taunted me at first, there were quite a few who lent me support later by giving me food and helping me buy my tools."
Manjhi died on 17 Aug 2007 at the age of 73, while suffering from gall bladder cancer in All India Institute of Medical Sciences (AIIMS), New Delhi. He was given a state funeral by the Government of Bihar.
Manjhi's deeds are referred to in the 2011 Kannada movie Olave Mandara directed by Jayatheertha. A supporting character in the 1998 Kannada movie Bhoomi Thayiya Chochchala Maga was based on Manjhi.
The first episode of Season 2 of the Aamir Khan hosted TV Show Satyamev Jayate, aired in March 2014, was dedicated to Dashrath Manjjhi. Aamir Khan and Rajesh Ranjan also met Bhagirath Manjhi and Basanti Devi, son and daughter-in-law of Manjhi and promised to provide financial help. However, Basanti Devi died due to inability to afford medical care on April 1, 2014.
In August 2015, a Hindi movie Manjhi - The Mountain Man was released and well received. The movie was directed by Ketan Mehta. Nawazuddin Siddiqui played the role of Manjhi along with Radhika Apte as Falguni Devi.
For his feat, Manjhi became popularly known as the 'Mountain Man'. The Bihar government also proposed his name for the Padma Shree award in 2006 in social Service sector. A stamp was released by India Post in the "Personalities of Bihar" series on 26th December 2016.
