 Road tunnels and technology in an operational perspective
Arild Petter Sovik, Tunntech Global News

This conference focused on tunnels as a vital links in any transportation network. Short periods of closure for maintenance or repairs always generate nuisance. Long periods of closure for renovations will logically lead to severe congestions. For too long, the tunnel community has accepted this nuisance and chaos as a natural side effect of tunnel operations. Should we accept this?  

Road authorities in South Africa are looking into how to renovate and improve operation and safety in the Huguenot tunnel, a 4 km single tube tunnel located at the national road (N1) near Cape Town. 

St. Pauli Elbtunnel opened in 1911 and is a combined pedestrian and vehicle tunnel in Hamburg, Germany. The over 400-meter-long tunnel was a technical sensation in the early 1900. The need for refurbishment has reached this amazing tunnel in Hamburg.

Life cycle and life cycle costs (LCC) aspects becomes more important and especially for complex tunnels with a high operation costs and challenges to keep open 24/7. Its important to consider these aspects in the planning and the design of the tunnel, and make sure this is a part of the evaluation of the different alternatives.
