Rockfall canopy south of Kaikoura traffic – night time closures extending to late February

4 MinutesBy NZ Trucking magazineDecember 8, 2020

Night time work to install a permanent rockfall protection canopy on SH1 between Peketa and the Parititahi Tunnels south of Kaikoura has been extended to late February 2021 (weather dependent).

Colin Knaggs, NZ Transport Agency manager at the North Canterbury Transport Infrastructure Recovery alliance (NCTIR), says the rockfall protection work is critical to keep road users safe.

“Safety work has been under way on this rockfall prone corner since July 2020, but there‘s still a fair way to go. This is a busy road for locals, freight and visitors – especially over summer – and we need to make sure that where possible work is done at night to keep any disruption to a minimum.”

While NCTIR works wrap up in Kaikoura at the end of December, the canopy project will continue into early 2021. Works have been extended following unexpected delays in the supply of some construction materials due to port strikes in Australia and Covid-19. There was also increased requirements for milling and rock removal from unforeseen fractured rock conditions, as well as some design changes in order to suit the physical conditions discovered on site.

The rockfall protection canopy will be the first of its kind to be installed in the Southern Hemisphere. It is expected to be completed by the end of February 2021 (weather dependent).

Daytime work on the rockfall protection will finish for the year on Saturday 19 December and traffic will be two-way for the Christmas/New Year break, from Sunday 20 December 2020 to Tuesday 5 January 2021. A speed restriction will be in place.

Night closures will recommence Tuesday 5 January with the closure timetable remaining the same.  Waka Kotahi thanks all drivers affected by these night closures for their patience over coming nights and the New Year.
