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.
Traffic Impact Assessments
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).
The largest section of the Waikato Expressway to bypass the city of Hamilton. This project requires the use of extensive barrier systems and some significantly detailed and complex TMP design around major interchanges. Parallaxx have been supporting the project since inception with complex Traffic Management design, barrier design, barrier installation and inspection, and Traffic Impact Assessments.
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.
As part of the suite of projects occurring in the Wynyard Quarter – numerous road upgrades and streetscape activities are beautifying some of the key roads in the area. The road upgrades must be staged in such a way to ensure access is maintained to all areas of the quarter, and public transport movements remain optimised. As more areas become finished and open, this staging challenge becomes harder and harder.
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
As part of the western ring route suite of projects the construction and traffic staging had to be developed to work in unison with the staging of the 2 existing projects Lincoln Road upgrade and the causeway upgrade. This involved upgrading the intersection and realignment of all ramps. Additional complexity was added when the Te Atatu Road corridor improvements project started
This project is almost entirely offline meaning the impact on the road corridor is via large vehicle movements (site access) and some service connections work only. The nature of the location however presented some unique road safety challenges in a high speed rural area not suited to accommodate large trucks moving to and from the site area.
Growth in and around Glen Innes in East Auckland meant that the existing power supply was being put under pressure, and increased capacity was required. Large trenches through bustling urban areas and through major intersection meant timing and clever TMP design were crucial.
