Eastern Busway

Rā Hihi is a critical part of the Eastern Busway project. Providing a direct link between Pakūranga Highway and Pakūranga Road, the flyover eases congestion around Pakūranga town centre and improves travel times while allowing construction of the busway beneath it to continue at pace. Rā Hihi (meaning sun's rays) crosses Tī Rākau Drive so drivers bypass one of the busiest intersections in New Zealand. It has 4 vehicle lanes — 2 in each direction.

The flyover is 600 metres long and 18 metres wide. It has 17 sections (spans) that are supported by 16 piers. The longest span reaches 40 metres over Tī Rākau Drive.

It opened 5 months ahead of schedule and came in $4 million under budget while remaining in scope. Time and cost savings came from multiple approaches. The biggest time saver was using cranes to move the temporary bridge support. Instead of assembling and then dismantling the supports, cranes were used to lift and shift them into place. This reduced the time needed for each bridge section from 8 to 10 days per span to just 2 to 3 days.

Smart technology was also used during construction. Wireless concrete sensors were used during concrete pours to check temperature and strength gain. The devices sent back data, in real time, which let the team know when the concrete was dry. This saved one month in total.

Work at Panmure Station transformed the area into a modern public transport interchange, improving connections between bus and rail services.

The station upgrade boosted public transport patronage by 275% over three years and has reduced travel times. With buses now running every 5–10 minutes on congestion-free lanes, it is now up to 17 minutes faster to get to Waitematā Station from Botany using public transport and 8 minutes faster from Pakūranga.

The improvements also include new cycle lanes, pedestrian paths, and better access to surrounding areas, supporting more sustainable travel choice and making active transport safer and more accessible.
