The bridge is 4.94 km long.
“The prime minister will inaugurate the bridge on December 25 which is also marked by the government as Good Governance Day,” the official told.
While former prime minister HD Deve Gowda laid the foundation stone for the Bogibeel bridge in January 1997, the work started only in April 2002 when former PM Atal Bihari Vajpayee inaugurated its construction.
With several deadlines having been missed over the past 16 years, the first freight train ran on it on December 3.
The Bogibeel Bridge is part of infrastructure projects planned by India to improve logistics in Arunachal Pradesh. This includes the construction of a trans-Arunachal highway on the north bank of the Brahmaputra river.
