Rock scaling next week Lewis Pass and later in March at Arthur’s Pass


Drivers on the Lewis Pass (SH7) route between the West Coast/ Nelson and Canterbury need to build in extra time to their journeys next week.

Rock scaling (removal of loose rocks) between Waipara and Boyle River will cause 30-minute delays Tuesday to Friday, 5 to 8 March, 7 am to 6 pm.

A week later, there will be rock scaling on the Arthur’s Pass route, SH73, between Greymouth/Kumara and Christchurch. This work between Springfield and Arthur’s Pass will run from Monday to Monday, 18 – 25 March, 7 am to 6 pm with up to 30-minute delays.

NZTA thanks all drivers and road users on these key mountain highways for their patience while this work is completed.
