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 Biggest project ever awarded at the time in New Zealand. The was the connection between the SH20 and SH16 by constructing a 2 2.4km tunnels one for each direction. This program and staging had to work with Causeway and St Luke’s project on SH16. Due to the nature of the intersection design and upgrade requirements there was significant challenges to keep the traffic moving.
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 per the NZTA website “one of the most significant single pieces of new road construction in the lower North Island”. And it is not an understatement. The project spans 27km from Mackays crossing to Linden. Most of the project was build in Greenfields but the tie in point has significant challenges due to the narrow carriageways to keep the traffic flowing while construction is happening.
A significant corridor heading to East Auckland (from the CBD) – Tamaki Drive has long been a major thoroughfare for all modes (especially cycling) and safety improvements have been desperately required for some time (especially at the intersection of Ngapipi Drive). With the multimodal environment and already safety-compromised intersection present – the TMP design and traffic staging of the project is a critical component to ensure overall safety is maintained whilst the construction progresses.
Construction of new widening on SH1 between Manukau and Papakura. This included adding at least one lane in each direction along the motorway, numerous new bridges, new ramps at the Takanini interchange whilst maintaining traffic flows on one of the busiest sections of the motorway network (significant peak flows each day, as well as weekends)
The SH20A section at Kirkbride Road remained the last significant bottleneck for travellers heading to and from Auckland Airport via SH20 and as such, was a significant undertaking to create a grade separated interchange. The result is a continuous journey through to Auckland Airport (or just short of it) through the NZTA network and an impressive achievement of consistent travel times through this corridor.
This is major safety improvement project along SH2 through the Bay of Plenty area. It involves widening of the existing two lane, two way SH. There are not significant shoulders and so working space is extremely tight. Two way traffic must be maintained at all times due to minimal alternate routes for detours
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 involves another new roundabout construction on a State Highway. This time at the intersection of SH1 and SH15 south of Whangarei. SH1 still carries high volumes of traffic, particularly heavy vehicles and we must maintain two way traffic flow at all times. High speeds and space constraints are the major challenges on this project
