Multi-million dollar safety upgrade for New Zealand tunnel

New Zealand transport Minister Simon Bridges has announced work is set to begin on a multi-million dollar fire deluge system that will improve safety and reduce the risk of lengthy closures at Lyttelton Tunnel south of Christchurch. The US$19.9 million (NZ$28.7 million) project is the largest project undertaken at the tunnel since it opened in 1964.

New Zealand transport Minister Simon Bridges has announced work is set to begin on a multi-million dollar fire deluge system that will improve safety and reduce the risk of lengthy closures at Lyttelton Tunnel south of Christchurch.


The US$19.9 million (NZ$28.7 million) project is the largest project undertaken at the tunnel since it opened in 1964. The contract has been awarded to McConnell Dowell, with work set to start in the coming weeks.

A fire sprinkler system is the most effective means of managing fire risk in the tunnel and is designed to control and contain a fire until fire services reach the scene. The project involves the construction of two reservoirs, two pump stations, and the installation of 9km of pipe work and 2,400 fire sprinkler nozzles throughout the tunnel.

The project is expected to be complete by December 2018.

    Radar can have distinct advantages in some transport-related situations as Colin Sowman found out during a visit to Navtech Radar. Despite tremendous advances in machine vision techniques, the accuracy and reliability of camera-based detection systems suffer during periods of poor visibility where other technologies may offer an alternative. Radar is one such technology. It too has seen significant development in recent years and according to Navtech Radar, the technology can often fulfil detection and moni
