Work is beginning on an integral and important piece of work within the Ara Tūhono – Pūhoi
to Warkworth Motorway Project requiring significant road layout changes north of the
Johnstones Hill Tunnels.
What is happening at the Southern Connection?
The Southern Connection works involve a four-stage construction sequence to connect State
Highway 1 (SH1) north of the Johnstones Hill Tunnels to the new motorway. The works will
enable the widening of SH1 north of the tunnels where it will eventually connect to the
section of new motorway still under construction.
Stage 2 requires SH1 southbound traffic north of the tunnel, to be temporarily transferred to
the existing northbound lane (refer map below). This will ensure the safety of our workers
undertaking these critical works and commuters using the existing roading network, whilst
limiting disruption to traffic flows, as far as practicable.
When and where will we be doing this work?
For the past couple of years, we’ve been building the new alignment alongside SH1. Now
we’re working to bring the two together. The new road layout on SH1, north of the
Johnstones Hill Tunnels will be in place from 10 November 2020 until late May 2021.
The road layout changes will be formed over a period of two nights on 8-9 November 2020
from 8:00pm – 4:00am. Stop/go traffic management will be in place to enable this to happen
Safety is our highest priority and the reduced speed limit of 60km/h will remain in place for
the duration of the works. While we will try to limit disruption to traffic flows, road users
should plan ahead and allow more time for their journey.
What does this mean for you?
We ask that drivers keep to the temporary speed limit for the safety of our work crews and
road users, drive to the conditions and don’t be distracted by work activity. Motorists may
experience longer travel times during this time. We advise planning ahead by allowing
extra travel time especially during the weekend and public holidays.

Thank you for your patience and support while we complete this important work. To help
plan for peak time travel, visit the Waka Kotahi NZ Transport Agency journey planner at Alternative routes are available via Hibiscus Coast Highway and
State Highway 16.
