Mahatma Gandhi Setu (also called Gandhi Setu or Ganga Setu) is a bridge over the river Ganga in Bihar, India, connecting Patna in the south to Hajipur in the north. Its length of 5,750 metres (18,860 ft) makes it the fourth-longest river bridge in India. It was inaugurated in May 1982 in a ceremony in Hajipur by then-prime minister Indira Gandhi. From 1982 to 2017, Mahatma Gandhi Setu was the longest bridge in India. Later, the Gandhi Setu rehabilitation project was undertaken to install triangular steel trusses on Mahatma Gandhi Setu.
