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.

    Widest bridge in the world Port Mann open in Vancouver
    Port Mann Bridge, designed to growing regional congestion and improve the movement of people, goods and transit throughout greater Vancouver, is now open for business. The widest bridge in the world, the Port Mann Bridge located in the metro Vancouver area, in British Columbia, Canada, features an Open Road Tolling (ORT) system, also called All Electronic Tolling (AET), which will ultimately cross all 10 lanes of traffic.

    Traffic to flow freely over world’s widest bridge
    Pete Goldin reports on a new Egis project in Canada, providing open road tolling operations for the widest bridge in the world. A bridge can present a bottleneck in a system of roads or it can support the smooth and unobstructed flow of traffic. Much depends on the bridge design, surrounding infrastructure and tolling system. By adding lanes and deploying open road tolling (ORT), the new Port Mann Bridge located in the metropolitan Vancouver area in British Columbia, will alleviate congestion at one of the

    Road space utilisation improves travel times, reduces costs
    For major road works schemes, necessary lane closures are timed to minimise congestion, most frequently at night and on weekends when traffic is at its lightest. As a result, rigid timetables are used in planning, programming and implementing work. In the UK, to calculate the expected traffic demand through roads works, historic profiles from the loop-based MIDAS (Motorway Incident Detection Automatic Signalling) system were used. These provided a valuable indicator of anticipated traffic behaviour but were
