CSP supplies the finishing touches to Lyttelton Tunnel project

Armorwire® Wire Rope Barrier is a legacy product

On 31 August the New Zealand Transport Agency (NZTA) will celebrate the 50th anniversary of the Lyttelton Tunnel’s construction and the opening of the tunnel’s new Control Building that was irrevocably damaged during the February 2011 earthquake. The tunnel will open to the public from 9.30am, allowing people to walk, skate or ride through it before it is officially opened to motorists. CSP played their part in the project by supplying Armorwire Wire Rope Barrier for the entrance of the tunnel - the finishing touches to a three year long project.

The Lyttelton road tunnel runs beneath the Port Hills to the south of Christchurch and links the city with Lyttelton Port. It was opened in 1964 and carries around 10,000 vehicles per day. At 1,970m it is the longest road tunnel in New Zealand.

While the tunnel itself was not damaged by the February 2011 earthquake the nearby Road Tunnel Administration Building - a Category I heritage building - suffered significant damage and was closed before finally being demolished in 2013. A new building has been constructed with work on the roadway also required.

“The Armorwire Wire Rope was the last part of the project,” explains Hamish Brixton, Sales Engineer for CSP. “Although there was nothing out of the ordinary on this job we are just happy to have played a small part in getting the tunnel up and running after a difficult few years – it’s been a bit of a shambles for a while.”

“It was an easy installation,” advises Jamie Clark, Director of J C Contracting. “There were two short runs of TL-4 Armorwire Wire Rope Barrier System with a weigh bridge in between. As always CSP were great to deal with. We are happy to see that the tunnel is finally back to normal.”
