Repairs to slip on SH1 south of Brynderwyn Hill


Waka Kotahi NZ Transport Agency advises of repairs to a slip on SH1 at the south side of the Brynderwyn Hill, caused by recent weather events.

The work will take place between 6am and 5pm so that workers have full visibility to ensure their safety.  No work will take place during the night or on the weekend. Work is planned to start on Tuesday 27th September, and is expected to be complete by Friday 30th September.

It is critical that the slip repairs are completed as soon as possible to avoid further movement which would impact the lane and require more invasive and lengthy repair work.

During the work, traffic management and a temporary speed limit of 30km/h will be in place between Atlas Quarries at the south side of the Brynderwyn Hill and the summit.

While SH1 will remain open, significant delays of up to 60 minutes are expected. We encourage road users to use the suggested alternate route via Kaiwaka Mangawhai Road to the south of the site and The Braigh in Waipu in the north. This route is expected to add 20 – 40 minutes to the journey. Please plan your journey at Waka Kotahi Journey Planner and allow time for the delays.

For maximum efficiency, general maintenance will be also undertaken while traffic management is in place at this location.

Work is conditional on weather events and other disruptions.

Buses and over-dimensional /heavy loads will be given priority through the stop/go closure, however we do encourage the use of the alternate route if at all possible.

Waka Kotahi thanks everyone for their patience.
