Sydney Orbital Network

The Sydney Orbital Network is a 110 kilometre [RTA Website [http://www.rta.nsw.gov.au/usingroads/motorwaysandtolling/index.html Motorways and tolling] ] motorway standard ring-road or orbital around the city of Sydney, the capital of New South Wales in Australia. 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. 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.

Motorways that make up the 110 kilometre orbital road

The Sydney orbital consist of several motorways and freeways, they are list below
* Eastern Distributor
* Southern Cross Drive
* General Holmes Drive
* M5 Motorway East
* M5 South Western Motorway
* Westlink M7
* M2 Hills Motorway

Tolling

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

Highway links

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

*Pennant Hills Rd - linking Sydney-Newcastle Freeway to M2 Motorway
*M4 Motorway - linking Great Western Highway to Westlink M7
*M5 Motorway - linking Hume Highway to General Holmes Drive
*King Georges Rd - linking M5 Motorway to Princes Highway, Southern Freeway and Wollongong

Proposed or missing freeway/motorway links

*Link to the F3 Sydney-Newcastle Freeway – The final stage of a motorway standard Sydney Bypass, a tunnel under Pennant Hills Road is in the planning stages. [RTA Website - F3 to M2 link. [http://www.rta.nsw.gov.au/constructionmaintenance/majorconstructionprojectssydney/f3tosydneyorbitallinkstudy.html F3 to Sydney Orbital link study SKM] ]
*Link to the F6 Southern Freeway – 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.
*Marrickville Tunnel – Proposal to link the orbital ring road at Port Botany with the M4 Motorway, to remove commercial traffic from inner west surface roads.
*M4 East – Extension of the M4 Motorway to the Anzac Bridge. This proposal has been reviewed and cancelled following stiff community opposition, which cited encouraging additional commuter traffic into the CBD, whilst removing little commercial traffic from the area.
