It is built across the Ganga River in Bihar. The bridge connects Patna in South Bihar with Hajipur in North Bihar and plays a vital role in transport, trade and regional connectivity. The bridge transformed movement between both regions after its opening in 1982. Its rehabilitation with modern steel truss technology has further strengthened its strategic importance for road transport and economic development in eastern India.<\/span><\/p>\n<h2><b>Mahatma Gandhi Setu<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Mahatma Gandhi Setu is a landmark engineering project that has remained a crucial transport link for Bihar for more than four decades. Its construction, rehabilitation, engineering design and economic importance make it one of the country&#8217;s most significant river bridges.<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Location: <\/b><span style=\"font-weight: 400;\">Mahatma Gandhi Setu is situated over the <\/span><a href=\"https:\/\/vajiramandravi.com\/current-affairs\/ganga-river-system\/\" target=\"_blank\"><b>Ganga River<\/b><\/a><span style=\"font-weight: 400;\"> in Bihar.

It remained the <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/longest-bridge-in-india\/\" target=\"_blank\"><strong>longest bridge in India<\/strong><\/a> from 1982 until 2017. Today, it is the fourth longest river bridge in the country.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Connectivity: <\/b><span style=\"font-weight: 400;\">The bridge serves as the primary road link between North and South Bihar.

The bridge was inaugurated by <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/prime-ministers-of-india\/\" target=\"_blank\"><strong>Prime Minister<\/strong><\/a> <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/indira-gandhi\/\" target=\"_blank\"><strong>Indira Gandhi<\/strong><\/a> in May 1982 after nearly ten years of construction.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Construction Cost and Delays: <\/b><span style=\"font-weight: 400;\">The project was initially awarded at \u20b923.50 crore. Due to <a href=\"https:\/\/vajiramandravi.com\/current-affairs\/thunderstorm\/\" target=\"_blank\"><strong>storms<\/strong><\/a>, shortage of cement, labour strikes and contractual disputes, the final construction cost increased to about \u20b987.22 crore.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Engineering and Structure:<\/b><span style=\"font-weight: 400;\"> The bridge consists of 45 intermediate spans of 121.065 metres each with end spans of 65.53 metres. It was built using cantilever segmental construction with precast concrete segments and separate upstream and downstream carriageways.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Road Design: <\/b><span style=\"font-weight: 400;\">The bridge was designed as a four lane structure with two independent carriageways. It provides a 7.5 metre wide roadway along with footpaths on both sides for pedestrian movement.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Structural Problems: <\/b><span style=\"font-weight: 400;\">Continuous overloading and inadequate maintenance caused cracks, damaged expansion joints, water leakage and deterioration of the concrete superstructure.

The damaged concrete superstructure was completely replaced with modern steel truss girders.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Largest Steel Bridge: <\/b><span style=\"font-weight: 400;\">The redeveloped bridge became India&#8217;s largest steel bridge. Around 67,000 tonnes of steel were used. It was the country&#8217;s first project where an existing concrete bridge superstructure was fully replaced with a steel truss system.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><b>Completion and Inauguration: <\/b><span style=\"font-weight: 400;\">The renovated western carriageway opened on 31 July 2020.
