Shipping Ministry discusses the Progress on Five Bridges across Brahmaputra River under NW-2

The Ministry of Ports, Shipping, and Waterways, led by Union Minister Shri Sarbananda Sonowal, has provided detailed information in the Rajya Sabha about the ongoing construction of bridges over the Brahmaputra River, which is part of National Waterway-2.

Five bridges are under construction across the 891-kilometer stretch of the Brahmaputra River from Dhubri to Sadia. This river was officially declared as National Waterway-2 in September 1988.

The construction of any bridge over a National Waterway necessitates obtaining a "No Objection Certificate" (NoC) from the Inland Waterways Authority of India (IWAI). This requirement ensures that the bridges meet the essential parameters of horizontal and vertical clearances, which are critical for maintaining safe navigation.
