Weaving a new cycleway through Auckland city centre involved the piecing together of numerous projects that each involved their own unique challenges. This project involved a worksite length of less than 200 metres, but yet presented significant spatial constraints, linemarking challenges and traffic management interventions.
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.
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.
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.
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.
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)
This State Highway and Bridge replacement in New Plymouth involved some well-thought out TMP design and staging in an area not familiar with major capital works traffic management. Parallaxx were an important partner to Fulton Hogan to provide accurate and detailed TMP design that ensured clear and precise staging overlap (particular around the new bridge) and maintained lane availability.
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
Noise wall improvements along SH16 and SH18 will offer much improved noise protection for neighbouring homes and businesses. With full functioning State Highways close by the challenge is to execute this remedial work whilst impacting the high volume roads adjacent.
