National Highway 206, often abbreviated as NH 206, was a former national highway in India, located entirely within the state of West Bengal. Under the old numbering system, which was revised nationwide around 2010, this highway served as an important arterial route connecting key districts.
The highway commenced at Burdwan (now Bardhaman), a major city in West Bengal, and proceeded westward to terminate at Bankura. Its approximate length was about 98 kilometers (61 miles). NH 206 played a vital role in connecting the agricultural heartlands of Burdwan district with Bankura district, facilitating trade, commerce, and passenger movement between these regions. It traversed through a mix of urban, semi-urban, and rural landscapes, contributing to the local economies along its route.
Following the comprehensive renumbering of national highways in India, which aimed to create a more logical and contiguous numbering scheme, the designation "NH 206" was abolished. The former alignment of NH 206 was subsequently integrated into new national highway designations. Specifically, the stretch of old NH 206 from Burdwan to Bankura now forms part of National Highway 114 (NH 114) and a small segment might also be related to National Highway 14 (NH 14) in the new system. This reclassification means that while the physical road continues to exist and serve its function, its administrative identifier has changed to reflect the updated national highway network.
