Inside of the North Bore tunnel (IMAGE) Stellenbosch University Caption This is the inside of the North Bore service tunnel to the Huguenot tunnel in the Du Toits Kloof mountains in the Western Cape, South Africa. An engineering feasibility study will determine the viability of establishing the Paarl Africa Underground Laboratory just off this tunnel as part of the South African National Roads Agency’s (SANRAL) plans to upgrade the North Bore tunnel to lower traffic volumes in the existing South Bore tunnel.
