General Information:

M1 / A1 is the principal coastal route through New South Wales, and forms part of the circumferential route around Australia.

The route varies greatly along its length and includes sections of rural highway, urban arterial road, divided rural highway and also motorway. The route also features several tunnels, located in the inner east, inner south and lower northern suburbs of Sydney and at Yelgun and Tweed Heads, at the northern end of the route in NSW. The route passes through forest, rural, residential, commercial and industrial areas.

Sydney Harbour Tunnel:

Built during the late 1980s, the Sydney Harbour Tunnel was built to provide additional traffic capacity across Port Jackson (Sydney Harbour), and helped alleviate traffic levels on the Sydney Harbour Bridge. The route also forms part of an eastern bypass of the Sydney CBD. The route is tolled.

The 2.3 kilometre Sydney Harbour Tunnel connects the Warringah Freeway on the northern side of Sydney Harbour to the Cahill Expressway, south of the harbour. It includes a one kilometre section below the harbour constructed by the immersed tube method. The Sydney Harbour Tunnel Company (SHTC) owns, operated and maintained the Harbour Tunnel until August 2022 when was transferred to public ownership. 2

Cahill Expressway:

The route features New South Wales first ever expressway, the Cahill Expressway built in the 1950s at Circular Quay. Stage 1 of the route features a dual deck, with roadway on the top and railway under, both passing over the Circular Quay ferry terminal on Sydney Harbour. 2

Eastern Distributor:

The Eastern Distributor forms the rest of the eastern bypass of the Sydney CBD and was built during the 1990s as a slot freeway, which is sunken below the surface of surrounding suburbs and streets. This route also features tunnels and is tolled.

The Eastern Distributor provides a high-quality road link between the Cahill Expressway at Woolloomooloo and Southern Cross Drive at Zetland. The motorway was funded and built by Airport Motorway Limited, which now operates, maintains and repairs the motorway until 2048, when it will revert to public ownership. The motorway is operated on Airport Motorway's behalf by Leighton Contractors. 2 The Eastern Distributor bypasses up to 19 sets of traffic lights. 3

Southern Cross Drive:

Southern Cross Drive was built during the beginning of Sydney's freeway era, and connects the Eastern Distributor with General Holmes Drive, and features some viaducts over swampy ground located near Kingsford Smith Airport.

General Holmes Drive:

General Holmes Drive was an expansion of existing roads around the southeast of Kingsford Smith Airport, the international airport for Sydney. It features a dual tunnel underneath the north-south runways of the airport and located close to Botany Bay. The route connects with The Grand Parade (A1) and also South Western Motorway (M5).

The Grand Parade:

The Grand Parade is a suburban arterial route that runs along the southwestern part of Botany Bay, and passes through mostly residential and commercial precincts, and as a result suffers from traffic congestion.

President Avenue:

Suffering traffic congestion similar to The Grand Parade, President Avenue connects The Grand Parade with the Princes Highway, for the journey to Sydney southernmost suburbs and beyond.

Princes Highway:

The Princes Highway was formed from a string of roads linking Sydney to the Illawarra, and then forming a coastal route to Melbourne and into South Australia. The section covered by A1 is in 2 pieces - between Kogarah and Waterfall in Sydney, and then Kiama near Wollongong through to the Victorian Border. The route is a mix of urban arterial road, dual carriageway and also rural highway.
