The Lane Cove Tunnel opened to traffic on 25 March 2007
The 3.6km tunnel is a key link in Sydney's orbital motorway network, connecting the Gore Hill Freeway with the M2 Motorway. The tunnel bypasses five sets of traffic lights on Epping Road. Motorists travelling between Falcon Street and the M2 can avoid travelling via the Pacific Highway and bypass up to 24 sets of traffic lights. This has resulted in quicker journey times between the city and Sydney's north-west.
The Lane Cove Tunnel has full electronic tolling and no toll booths.
Lawrence Hargrave Drive
Since the opening of Sea Cliff Bridge in December 2006 the bridge itself has become a major attraction for visitors to the Illawarra including drivers, cyclists and pedestrians.
Sea Cliff Bridge was originally designed to include a 2.5metre wide shared pedestrian /cycleway as a local connection between the villages of Coalcliff and Coledale. However, the unprecedented use of the pedestrian/cycleway has highlighted the need for the Roads and Traffic Authority to review the way the bridge accommodates all users, and in particular pedestrians and cyclists.
As a result of these investigations several changes will be made to improve safety for pedestrians whilst still accommodating cyclists.
These changes will be implemented by the end of September 2006.
The bridge has been constructed using two different methods. A balanced cantilever bridge (similar to the Mooney-Mooney and Pheasants Nest bridges) extends from the existing road at the southern headland and curves to join an incrementally launched bridge (similar to the Woronora Bridge). This joins the existing road at the middle headland.
The bridge, to the east of the existing road, provides a long-term solution for all road users. The project also includes various geotechnical and stabilisation works along the cliff line.
Westlink M7
The
Westlink M7 was completed and open to traffic on 16 December 2005.

The 40 kilometre Westlink M7 links the M2 at West Baulkham Hills, the M4 at Eastern Creek and the M5 / Hume Highway at Prestons and bypasses 48 sets of traffic lights.
Westlink M7 uses a distance based tolling system and is a fully electronic tollroad with no toll booths.
North Kiama Bypass
North Kiama Bypass was officially opened on Saturday 26 November 2005.
The road was opened to traffic on Monday 28 November.
The $179 million, 7.6 kilometre North Kiama Bypass is on the Princes Highway near Dunmore. It improves safety and travel conditions by eliminating a winding section of the highway at Minnamurra as well as removing through traffic in residential streets in Bombo, Kiama Downs and Minnamurra.
The bypass was funded by the NSW Government, with the Commonwealth Government contributing $34 million to the project.
