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.
The section of very busy State Highway heading south from Mount Maunganui has had its capacity and function stretched for some time. A major upgrade was required but to construct – would be a challenge of conflicting needs. A keen balance would be required between construction productivty and space maximisation, and disruption (to vehicles, pedestrians, cyclists and even the railway).
This project is one part of the overall City Rail Link Project – the largest construction project ever undertaken in New Zealand. This component required the construction of twin cut-and-cover tunnels under Albert St in Auckland’s CBD, including traversing the busy Customs St Intersection. The challenge of major construction in New Zealand’s busiest commercial area was very real.
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
This project is one part of the overall City Rail Link Project – the largest construction project ever undertaken in New Zealand. The C5 section involves the upgrade of the Normanby intersection and level crossing. An upgrade of the Porters Ave level crossing is required. All this needs to tie in with the C3 program and staging.
A significant rebuild/realignment of State Highway 3 in the Manawatu, this alliance project calls for some innovative traffic management solutions to deal with the challenging local road network (that is currently being used as the defacto state highway). A high volume of earthworks also proves a challenge for entry and egress to site.
A mammoth project installing a new major interceptor pipeline under Auckland. Parallaxx are charged with assisting with TMP design and overall TTM methodology, particularly around the significant shaft areas along the alignment length.
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
The southern-most part of the Waikato expressway – the Cambridge section bypasses Cambridge township and became New Zealand’s first 110km/hr road when the Land Transport Rule was updated in 2017. The development of a new State Highway corridor through existing areas resulted in numerous challenging intersections, crossings and grade separated solutions.
