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

|

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

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

“Safety work has been underway 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 Kaikōura 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.
