Prime Minister Narendra Modi on Tuesday inaugurated India’s longest railroad bridge, Bogibeel bridge, in Dibrugarh Assam.

The bridge was inaugurated 21 years after its foundation stone was laid. The double-decker bridge, the fourth across the Brahmaputra, has two railway lines on the lower deck and a three-lane road on the upper deck

It’s  strong enough to withstand movement of even heavy military tanks. It’s India’s only fully welded bridge for which European welding standards were adhered to for the first time in the country.
