The Huguenot Tunnel in South Africa 🇿🇦 is the longest road tunnel in Africa .
The 3.9km tunnel was officially opened in March 1988 and provides a shorter route, 11km less than the original route over the pass. According to the Average Annual Daily Traffic (AADT), the tunnel accommodates over 12,000 vehicles daily. Located near Cape Town, South Africa, the tunnel extends the N1 national road through the Du Toitskloof mountains, linking Paarl and Worcester. This route offers a significantly safer, faster (between 15 and 26 minutes), and shorter (by 11km) alternative to the old Du Toitskloof Pass, which traversed the mountain.
