Sydney Orbital Network - Motorways That Make Up The Orbital Road

Motorways That Make Up The Orbital Road

The 110 km Sydney orbital consists of several motorways and freeways, they are listed below:

• Eastern Distributor
• Southern Cross Drive
• General Holmes Drive
• M5 Motorway East
• M5 South Western Motorway
• Westlink M7
• M2 Hills Motorway
• Lane Cove Tunnel
• Gore Hill Freeway
• Warringah Freeway
• Sydney Harbour Tunnel (or Sydney Harbour Bridge and Cahill Expressway)

The major sunken/underground sections of the orbital are:

• Sydney Harbour Tunnel
• Eastern Distributor
• M5 East tunnel
• Epping Tunnel (M2 Hills Motorway, although not really a major tunnel)
• Sunken Section of the M2 Hills Motorway (The trench between Epping Road)
• Lane Cove Tunnel

The major elevated sections are:

• Parts of the Westlink M7
• Parts of Southern Cross and General Holmes Drive (past the airport)

The widest part of the orbital is the Warringah Freeway approach to the Sydney Harbour Bridge, the longest tunnel is the M5 East tunnel, and the largest interchange is the Light Horse Interchange between the M4 and M7. It would cost over $30AU to take the whole orbital without exiting once. The average width of the Orbital is 2 lanes (most of the M5, M7, Lane Cove tunnel and M2 is two lanes).
