Map of the Sydney orbital network — The Sydney orbital network.

The Sydney Orbital Network is a 110 kilometre^[1] motorway standard ring road or orbital around the city of Sydney, the capital of New South Wales in Australia. It runs north from Sydney Airport, underneath the CBD to the North Shore, west to the Hills District, south to Prestons and then east to connect with the airport. Much of the road is privately owned and financed by tolls.

History

Planning for this beltway, orbital or ring road began as early as 1962 under the "county of cumberland scheme" (CCS) and well talked about as far back as 1944. Then from 1973 to 1989 things started to take shape with new sections opening-up and then further advancing by 1999. In 2007, the Lane Cove Tunnel opened, completing the orbital network.

Motorways that make up the orbital road

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

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, a 4-level stack. It would cost over $30AU to take the whole orbital without exiting once. The average width of the Orbital is 3 lanes in each direction (The M7 and Lane Cove Tunnel are 2 lanes in direction, however the M2, Gore Hill Freeway and M5 are 3 lanes each way while the Warringah Freeway is between 6-8 lanes each way for its short duration of around 3km).

Tolling

The Sydney Orbital Road Network consists of a number of roads built by private companies: tolling is unavoidable when using the road network.

Road	Direction	Toll Collection Method	Toll Pricing	Price	Operator
Eastern Distributor	Northbound	Electronic	Flat rate	$5.50	Airport Motorways
M5 South Western Motorway	Both	Electronic / Cash	Flat rate	$4.40	Interlink Roads
Westlink M7	Both	Electronic	Distance based	$0.3673/km, $7.35 Cap	Transurban
M2 Hills Motorway	Both	Electronic	Flat rate	$6.05	Transurban
Lane Cove Tunnel	Both	Electronic	Flat rate	$3.01	Transurban
Sydney Harbour Bridge	Southbound	Electronic^[2]	Time based	Weekdays $3.00 (9.30am - 4pm) $4 (6.30am - 9.30am, 4pm - 7pm) $2.50 (7pm - 6.30am); Weekends $3 (8am - 8pm) $2 (8pm - 8am)	RMS
Sydney Harbour Tunnel	Southbound	Electronic	Time based	Weekdays $3.00 (9.30am - 4pm) $4 (6.30am - 9.30am, 4pm - 7pm) $2.50 (7pm - 6.30am); Weekends $3 (8am - 8pm) $2 (8pm - 8am)	RMS

Highway links

Intercity highways are linked to the Orbital, moving traffic away from the old busy National Routes. They are:

Pennant Hills Rd - linking M1 Pacific Motorway, Newcastle and Brisbane to M2 Hills Motorway
M4 Western Motorway - linking Great Western Highway and Bathurst to Westlink M7
M31 Hume Motorway - linking Melbourne and Canberra to M5 South Western Motorway and Westlink M7
King Georges Rd - linking Princes Highway, M1 Princes Motorway and Wollongong to M5 South Western Motorway

Proposed or missing freeway/motorway links

Link to the M1 Pacific Motorway – The final stage of a motorway standard Sydney Bypass, a tunnel under Pennant Hills Road is in the planning stages.^[3]
Link to the M1 Princes Motorway – At present, there are no plans to complete this link as freeway standard. 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. This still leaves a considerable length of the corridor built out, which will require great expense to resume, or tunnel beneath.
WestConnex – A proposal that incorporates the M5 duplication project and the M4 East extension of the M4 Motorway to the M5 South Western Motorway, involving a cutting along Parramatta Road, a tunnel from Taveners Hill to St Peters and a surface motorway to the M5 at Arncliffe.
