The Huguenot Tunnel is a toll tunnel near Cape Town, South Africa. It extends the N1 national road through the Du Toitskloof mountains that separate Paarl from Worcester, providing a route that is safer, faster (between 15 and 26 minutes) and shorter (by 11 km) than the old Du Toitskloof Pass travelling over the mountain.

History[]

View of new road into Huguenot Tunnel

An idea for a tunnel through the Du Toitskloof Mountains was conceived in the 1930s but was put on hold due to the outbreak of World War II.[1] The idea developed into a pass over the mountains, the Du Toitskloof pass, using the labour of Italian prisoners of war between 1942 and 1945 and continued with ordinary labour until its completion in 1948.[1] Geological surveys and design started in 1973, and excavation followed in 1984, tunneling from both ends using drilling and blasting.

Construction[]

There were two phases to the tunneling, the first a pilot tunnel to examine the routes geographical obstacles.[1] The second phase bored a 5 m tunnel through granite rock as well as the construction of portals, drainage and ventilation tunnels.[1] The two met with an error of only 3 mm over its entire 3.9 km length. The tunnel was finally opened on 18 March 1988.[1]

The tunnel is maintained by Tolcon, a subsidiary of the Murray & Roberts construction company.[2] The tunnel was constructed by Hochtief Construction AG and Concor Holdings.

Current plans[]

Currently the tunnel carries one lane of traffic in each direction. Plans are underway to open a second unfinished tunnel, the "northern bore", to carry eastbound traffic. This will allow for two lanes of traffic in each direction, with each tunnel carrying traffic in one direction only.[3][4]

In 2002, traffic peaks occurred during Easter (a record on 26 April 18 200 vehicles) and the December school holidays (12 000 vehicles per day).

Toll[]

The toll as proclaimed on 1 March 2019[5] was (in South African Rand):

  • Light Vehicles: R42.50
  • 2-axle heavy vehicles: R118
  • 3 and 4-axle heavy vehicles: R185
  • 5 and more-axle heavy vehicles: R300

The tunnel has 13 video cameras that feed into an automatic , which can sound alarm devices for any of the following conditions:
