Trans-Kalahari Corridor Trans-Kalahari Corridor The Trans-Kalahari Corridor is a paved highway corridor that provides a direct route from Walvis Bay and Windhoek in central Namibia, through Botswana, to Johannesburg and Pretoria in Gauteng province in South Africa. It initially cost approximately 850 million Namibian dollars (US$115 million) and was officially opened in 1998. The corridor also includes railway lines from Walvis Bay as far as Gobabis in Namibia, and from Johannesburg as far as Lobatse in Botswana. Connecting the two railway lines has been discussed since 2010, and an agreement between the two countries was signed in 2014, but the project has
Kalahari Craton by accretion and had formed a Proto-Kalahari Craton by 1.75 Ga. During the period 1.4–1.0 Ga subduction occurred along the northwest margin followed by continental collisions along the eastern and southern margins. By this time enough Mesoproterozoic crust had accreted to transform the Kalahari Craton. At 1.11 Ga, during the assembly of the supercontinent Rodinia, the Kalahari Craton was affected by the Umkondo-Borg Large Igneous Province. At 1.15–.98 Ga the Kalahari Craton collided with the eastern margin of Laurentia. Kalahari Craton The Kalahari Craton is a craton, an old and stable part of the continental lithosphere, that occupies large portions
