With close to 25,000 vehicles estimated to use Te Aranui o Te Rangihaeata – Transmission Gully every day, the importance, safety and regional resilience of this section of State Highway 1 continues to be appreciated.
In the last two years, the motorway has also led to some significant improvements in network performance, including:
Mark McKenzie, programme delivery manager for public private partnerships and special projects at NZ Transport Agency Waka Kotahi, says Transmission Gully is a piece of infrastructure that continues to play a key role in our state highway network.
“It’s great to see its contribution towards network reliability continue. It has proven to provide a more resilient route in and out of Wellington, more reliable journeys, secure freight connections, as well as improved safety for all who use the wider network,” McKenzie says.
“As we celebrate this milestone, I’d like to remind motorists that while the road might look finished, there is still work that needs to be completed. We’ll keep working with our project partners to ensure the road can continue to make an enormous difference to the way we get around."
Within its first year of operation Transmission Gully had several economic benefits for New Zealanders.
Economic benefits are gained by determining the cost savings arising from reduced congestion and emissions, improved reliability, and user safety. Across these areas, the road has an estimated economic cost saving of $59.3 Million – and we can assume this has increased over the past year.
Transmission Gully was also built to high safety and operational standards.
Since it opened, there have been zero deaths or serious injuries along the motorway – despite there being approximately 115 incidents where the median and side barriers have been hit.
