The tunnel that 12,000 vehicles pass through daily almost became a road over the mountain instead. In the 1930s, engineers first conceived of boring through the Du Toitskloof Mountains to connect Paarl and Worcester, but World War II derailed the plan. Rather than a tunnel, the wartime effort produced a mountain pass, built partly with Italian prisoner-of-war labor between 1942 and 1945. The pass opened in 1948, and for forty years it carried the N1 national road over the peaks. The tunnel idea did not die -- it simply waited. Geological surveys and design work began in 1973, excavation started in 1984, and when the Huguenot Tunnel finally opened in 1988, it compressed an hour of mountain driving into a few minutes underground.

During holiday peaks, that number can nearly double -- 22,500 vehicles squeezed through on busy days, with a record 18,200 on a single April day in 2002. Managing this volume through a two-lane tunnel req...

Huguenot Tunnel: The Pass Forgotten, the Mountain Endures

The pass was renumbered from N1 to the regional R101, and through-traffic vanished almost overnight. But the mountains themselves remain unchanged. Du Toits Peak still rises to 1,995 meters ...
