The Hunter Street station will feature multiple underground pedestrian connections, including a nearly one-kilometre-long walkway beneath central Sydney, linking the city’s western and eastern sides.

Construction of the final southwest section of the M1 line is expected to open next year, while a planned metro link to Western Sydney Airport faces potential delays until December 2027.

The new tunnels will be approximately eight metres wide to accommodate lifts and escalators, significantly improving accessibility and passenger flow.

Sydney Metro CEO Peter Regan highlighted that these underground connections will facilitate efficient movement and connect four major transport hubs, easing city transit.

This underground link will include the 180-metre Wynyard Walk near Barangaroo and connect four railway stations, including a new large metro station beneath Hunter Street.

The underground walkway will allow pedestrians to cross city streets while staying dry during wet weather, similar to systems in Toronto, Montreal, and Sapporo.

The project will create a comprehensive underground network, including a large station beneath Hunter Street, to improve connectivity across Sydney.

Architect Philip Thalis emphasized that the underground stations will serve as functional public spaces that enable smooth transfer between different modes of transport.

By 2036, over 10,000 people per hour are expected to pass through Hunter Street station during peak times, increasing to 35,000 in the coming decades.

The Sydney Metro West line, stretching 24 kilometres from the CBD to Parramatta, is scheduled to open in 2032 as part of Sydney’s three independent metro lines.
