The final project along Auckland’s North Western Motorway as part of the NZ Government’s ‘Western Ring Route” corridor. The project aimed to connect the previously completed SH16/SH18 Hobsonville Interchange and Lincoln Road Interchange upgrade projects. 3 seperate major structural replacements (2 overbridges, one bridge over water) meant multiple work fronts and in some places a very tight corridor.
The SH16 Causeway Upgrade project spans the 4km stretch between Te Atatu interchange and Great North Road Interchange. The construction team was challenged to maintain traffic flows for the 90,000+ vehicles through the congested SH16 corridor while widening in both directions and raising the motorway by 1.5m to accommodate the rise in sea levels.
This project is one part of the overall City Rail Link Project – the largest construction project ever undertaken in New Zealand. The C3 section spans from Albert street all the way to Mt Eden including the construction on the 3 stations at Albert street, Pitt street and Mt Eden
Construction of new culverts under Wolverton Street near New Lynn. Wolvert Street is a four lane urban arterial road that carries signficant volumes of traffic to and from SH20 (part of the Auckland Motorway network). The project requires excavating through the road to build the new culverts. Whilst still maintaining traffic flows – it is an ongoing project in the early stages
A major rising main (pipeline) installation through the Pakuranga Road / Panmure Bridge / Lagoon Drive corridor which carries in excess of 40,000 vehicles per day. Coupled with Auckland’s only tidal local road (Panmure Bridge) and a 6m+ wide working space requirement – we were faced with a significant spatial challenge requiring innovative ideas.
The first of the project that kicked off NZTA’s “Western Ring Route”. Starting back in 2011, with the replacement of Selwood Road Bridge the Lincoln Road Interchange Upgrade started the complex, narrow and challenging work of upgrading a functioning high capacity motorway whilst maintaining close to full function. Parallaxx joined on the journey providing TMP design and fulfilled the role of Traffic Manager for a period as well.
The section of this project currently under construction is from Snell’s Beach to Algies Bay. The route travels through urban and high speed rural areas, and the method of construction requires the work site to move constantly along the road. This poses challenges for maintaining safety and using temporary barrier systems
Downer were awarded the contract for this project right before Christmas 2019, with a start date of 27th December 2019 and a very ambitious completion target of the end of February 2020, to fall in line with a major change in bus routes throughout the central city. The project involved a major upgrade of the Victoria St/Wellesley St/Halsey St intersection, as well as kerb buildout, new bus stops and footpath widening along a 800m long section of road to provide for dedicated cycle lanes in both directions.
The Te Atatu Road Corridor Improvements project involved providing additional bus lanes along Te Atatu road and upgraded pedestrian and cycle lane facilities and full depth pavement reconstruction. This corridor was severely congested with Vehicles, Shops and schools and additional community services.
The St Lukes cycleway safety improvements will make it safer and easier for pedestrians and cyclists to cross the motorway ramps and St Lukes Road, and connect to the popular SH16 Northwestern Cycleway. Many of the project areas where situated alongside the motorway itself as well as on-ramps and off-ramps meaning major closures.
