The four Hex River Tunnels consist of a twin tunnel of 0.5 kilometres (0.31 miles) and three single tunnels of 1.1 kilometres (0.68 miles), 1.2 kilometres (0.75 miles) and 13.5 kilometres (8.39 miles), on the Hexton railway route between De Doorns and Kleinstraat through the Hex River Mountains of the Western Cape Province, South Africa. The line, which connects De Doorns in the Hex River valley with Touws River in the Great Karoo, is part of the main rail route between Cape Town and Johannesburg. Of the 30 kilometres (18.64 miles) of track, 16.8 kilometres (10.44 miles) are underground. Construction of the line eliminated the bottleneck of the Hex River rail pass.[1][2][3]
