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.
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 significant rebuild of a major prison in the Waikato region that you wouldn’t think would have too many traffic management challenges however the precarious interseciton between SH3 and Waikeria Road says different. The construction floods the intersection with a significant increase in heavy vehicle movements, inflaming the already challenging safety environment.
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 Wynyard Quarter area has been a developing part of downtown Auckland for some time. With the obvious streetscape improvements comes significant underground utility improvements. Range of these upgrades are across the Wynyard Quarter area. With significant upright construction and other road improvement works – this means competing for workspace and overlapping worksite environments are almost guaranteed.
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 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
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.
