National Waterway (NW)-57 (River Kopili) was operationalised on August 2, 2025, marking the resumption of intra-state waterborne freight transport in Assam after more than a decade. The inaugural cargo trial involved the self-loading vessel MV V.V. Giri, which transported 300 metric tonnes of cement from M/s Star Cement along the 300 km route on the Kopili river (NW-57) and Brahmaputra river (NW-2), with a voyage time of about 12-14 hours. With this development, more than 1,168 km of NWs in Assam have become operational.
