National Highway 73 (NH 73) is a National Highway in India. This highway runs in the Indian state of Karnataka. It starts from sea port city of Mangaluru (Mangalore) and ends at Tumakuru.[1] Even though named as national highway the road is narrow and prone to landslips and falling of trees in Charmady ghat section of Western ghats.[2] This highway was previously part of national highways 48, 234 and 206 but subsequent to rationalisation of national highway numbers of India by Gazette notification on 5 March 2010 it was changed to National Highway 73.[3]
