Motorway Proposed or missing freeway/motorway links M6 Motorway – A proposal that links the New M5 Tunnels and the southern suburbs of Sydney, as the M6 Motorway. The only section which was built is the Captain Cook Bridge and its approaches. Land is still reserved north of this point through Sandringham, and south through the Royal National Park. In October 2017, the government announced it will proceed with Stage 1 of the F6 extension, which will run via two 4 km tunnels linking the New M5 tunnels at Arncliffe to President Avenue at Kogarah. In October 2019, the government announced a name change of the extension to M6 Motorway and also confirmed the completion date of Stage 1 would be pushed back to late 2025, with major construction to begin by early 2022.
