SH1 and SH16 summer works – December 2024 to April 2025

This summer NZ Transport Agency Waka Kotahi will be carrying out three essential maintenance projects on the Central Auckland motorway network. We appreciate that these works will be disruptive to motorists and the community. These dates have been chosen because traffic volumes are lower-than-normal during this period, which will help to reduce disruption. To avoid delays we highly recommend using alternative routes where possible.

• SH1/ SH16 Central Motorway (Spaghetti) Junction - 26 December 2024 to 6 January 2025
• SH1 Auckland Harbour Bridge - 26 December 2024 to 6 January 2025
• SH16 Port area summer works – The Strand, Stanley Street and Gladstone Road – 19 January through to April  2025

SH1/SH16 Central Motorway (Spaghetti) Junction

From 9pm Thursday 26 December 2024 to 5am Monday 6 January 2025, NZTA will be replacing a bridge joint on the State Highway 1 (SH1) southbound lanes approximately 40 metres north of Grafton Road overpass on SH1. This work is weather dependent and advertised dates may change.

Traffic management

Day works (6am to 9pm):There will be lane restrictions on State Highway 1 southbound from Hobson Street on-ramp to Grafton Road on-ramp.

Night works (9pm to 6am):There will be a full southbound closure on State Highway 1 from Victoria Park Viaduct to Grafton Road on-ramp.

Link and ramp closure and recommended detours

Day and night ramp and link closures (24/7)

• SH1 Symonds Street southbound on-ramp: Continue up Symonds Street and follow the detour via Khyber Pass Road to the Khyber Pass Road southbound on-ramp.
• SH16 eastbound to SH1 southbound link: Exit at Newton Road and detour via Newton Road and Khyber Pass Road to SH1 Khyber Pass Road southbound onramp.

Night-only ramp and link closures (9pm to 6am)

• Main detour for SH1 southbound: Take the SH16 Port link and exit at Wellesley Street East. Use the Grafton Road southbound on-ramp to link back to SH1 southbound. You can also use this detour to bypass the work during the day.
• CBD to SH1 southbound: Detour via Hobson Street, Pitt Street, Karangahape Road, Symonds Street and Khyber Pass Road to the Khyber Pass Road southbound on-ramp.

SH1 Auckland Harbour Bridge

From 2am Thursday 26 December 2024 to 5am Monday 6 January 2025 NZTA will be carrying out several maintenance activities on the Auckland Harbour Bridge, including resurfacing of lanes, and maintenance underneath the bridge. There will be lane restrictions 24/7 but traffic will still be able to travel in both directions at all times.

We use a specialist surfacing system on the steel decks of the clip-ons, which takes two to three days to cure. During this time there may be no one working on the lanes, but we will still be working underneath the bridge.

During work on southbound clip-on lanes (1 & 2) Shelly Beach Road off-ramp will be closed and Shelly Beach Road will be closed from Westhaven. Signposted detours will be in place.

During work on northbound clip-on lanes (1 & 2) Curran Street on-ramp and Stafford Road off-ramp will be closed. Signposted detours will be in place.

There will also be ongoing maintenance work over the summer period from 24 November 2024 to 27 March 2025, excluding the above period when we are carrying out other work over Christmas and New Year. These works will be carried out at nighttime.  Traffic will still be able to travel in both directions at all times.

SH16 Port area summer works – The Strand, Stanley Street and Gladstone Road

From 19 January to April 2025 we will be carrying out three projects (The Strand rehabilitation, Strand Optimisation Project – stage 1 improvements and Commercial Vehicle Safety Programme) under a combination of weeknight shifts and Super Weekends. By combining these projects, we remove the need to return to the area later in the year and extend the disruption.

Because these projects involve paving and are weather dependent it is best carried out during the warmer months (January to April).

Things to note:

• We appreciate that residents and businesses may experience noise disruptions and vibrations at various stages through the project. We will be monitoring this closely to ensure we are working within council regulations.
• Businesses will be open along The Strand, and pedestrian access will be available throughout the duration of works. Street parking may not be available but access to off-street parking for residents and businesses will still be available unless work is being carried out directly in front of the premises. Please check with business about parking before visiting.
• Work during the weeknights will begin on Sunday 19 January between 9pm and 5am. Preparation work may be carried out the week before (12 to 16 January). There will be lane restrictions, but traffic will be able to travel in both directions along SH16.
• Super weekends will start on Friday 31 January and run over four weekends along The Strand. Super Weekends will begin 9pm Fridays and finish by 5am Mondays. During the Super Weekends there will be a full westbound closure along The Strand. Please follow the recommended detour via Quay Street, Tangihua Street and Beach Road. Alternatively, you can use Gladstone Road, St Stephens Ave and Parnell Rise (not suitable for heavy vehicles).
• Expect delays travelling through the area while work is being carried out.
