Please note the tunnel will be closed on Sunday 24 February, Monday 25 February and Tuesday 26 February between 11pm and 4am to test the new fire protection system inside the tunnel. There will be 10 minute openings on the hour to clear traffic.
The tunnel will be open for emergency services at all times.
In addition to these works there will be work undertaken on SH74 (Tunnel Road), replacing some guard rail and other bridge works. Lyttelton bound traffic will be unaffected. Traffic leaving the tunnel towards Christchurch will have to exit onto SH76 Port Hills Road and follow the detour route.
Work has started on installing a modern fire protection Deluge system in the Lyttelton Tunnel that will improve safety for all tunnel users.
This $28.7 million project is being delivered by the NZ Transport Agency on behalf of the government, and is expected to be completed by the second quarter of 2019.
A Deluge system is the most effective way of managing fire risk in the Lyttelton Tunnel. The system that will be installed is designed to control and contain a blaze until fire services arrive.
From June to September, there will be a series of late night one-lane tunnel closures needed for Christchurch City Council contractors working on phase two of the Lyttelton Harbour wastewater upgrade project.
The contractor is working closely with NZ Transport Agency to co-ordinate closures with the $28.7 million Lyttelton Tunnel fire protection upgrade project to minimise the overall number of one-lane closures and disruption to motorists. Work at the tunnel roundabout in Lyttelton is required for laying wastewater pipes.
