Australia’s deepest road tunnel, the 9km NorthConnex in Sydney, dives 90 metres underground at its deepest points, is monitored by 850 CCTV cameras, including PTZs, with 750 cameras inside the tunnel and another 100 cameras installed on the approaches.

The solution is thought to incorporate Pelco PTZs, a Genetec Security Centre head end and FLIR analytics, with the Genetec solution staged by Hills, and the cabling handled by a contractor on behalf of Lend Lease.

The CCTV system is monitored 24/7 and is a vital element of traffic flow monitoring and communications in such a deep road system, as well as helping the NorthConnex team coordinate incident response as efficiently as possible.

There are 5000 LED lights inside the tunnel, delivering a reduction of carbon emissions of around 83,000 tonnes a year, as well as 140 jet air fans, 46km of heat sensing fibre optic cabling that triggers a zoned sprinkler system, as well as 400 addressable signs and a PA system.

According to NSW Premier Gladys Berejiklian said the project injected $4 billion into the economy and had created more than 8000 jobs.

“Even through the darkest months of the pandemic, this project kept pushing forward,” Ms Berejiklian said.

Using the tunnel will save motorists about 15 minutes on the trip between the M1 Pacific Motorway at Wahroonga and the M2 Motorway at West Pennant Hills and allow vehicles to travel across Sydney from North to South without meeting a single traffic light.
