Which Indian highways take you across the greatest distances? Think of four road trips across India: each has a start, an end, and a total length. First, NH 44-from Srinagar to Kanyakumari-runs roughly 4,112 kilometres, making it the longest major north-south route. NH 27 then goes from Porbandar to Silchar, about 3,507 kilometres west to east. NH 48 links Delhi to Chennai, roughly 2,807 kilometres. NH 16 connects Kolkata to Chennai, about 1,711 kilometres along India's eastern side. These are broad corridors, so sources may vary slightly. Now see all four: NH 44 is the longest, while the others run across India in different directions. So which highways cross India the farthest? They are road trips from Srinagar to Kanyakumari, Porbandar to Silchar, Delhi to Chennai, and Kolkata to Chennai-thousands of kilometres linking distant regions.
