Waka Kotahi NZ Transport Agency is advising drivers the second and final weekend of works to complete a concrete pour as part of the Northern Corridor Improvements (NCI) project is taking place this weekend.
To prepare for the daytime works, a full closure of State Highway 1 (SH1) southbound between Greville Road and Constellation Drive will be required overnight on Saturday 4 & Sunday 5 December to install and remove temporary lane barriers. Detour routes will be available.
Daytime delays are then expected on Sunday 5 December as the work is carried out.
Restrictions will apply during the following times:
Overnight full closure:
Day works – lower speed limit in place:
Overnight full closure:
During the daytime works temporary lane barriers will be used to detour vehicles around either side of the work area, with a 50kmph speed limit in place.
The team will be completing a concrete pour on the future SH1/SH18 underpass and need to ensure vibrations from passing vehicles is kept to a minimum.
Waka Kotahi encourages drivers to plan ahead and avoid the Albany and Rosedale area if possible.
For people who need to travel through the area, Waka Kotahi advises drivers to choose their lane much earlier than usual and look out for messaging on overhead and electronic signs.
Motorists who want to exit SH1 at Constellation Drive will need to use the left lane only.
An express lane to the right of the work area will also be operating for people wanting to continue their journey south towards the city.
Drivers will not be able to exit State Highway 1 at Constellation Drive if they are in the right-hand lane.
We understand the expected delays will be frustrating for drivers, but due to the preparation needed, crew were unable to undertake this work during higher Alert Levels.
It’s important the NCI team are able to complete the work now, to minimise disruption ahead of the opening of Auckland’s borders and the busy summer months.
When complete, the underpass will provide a direct motorway to motorway connection for people travelling from the north and wanting to head west, completing the Western Ring Route.
