Key features of the project

The upgrade of the Princes Highway between Oak Flats and Dunmore will complete the Government’s commitment to provide a four lane highway from Sydney to the south of Kiama by 2010. Its key features include:

• A four lane divided carriageway on the Princes Highway between Oak Flats and Dunmore.
• The upgrade of Shellharbour Road to four lanes completing the final section of the multi-lane Shellharbour Road to Wollongong.
• A grade separated interchange at Shellharbour Road.
• The extension of the on-road cycleway network and new dedicated pedestrian and cyclist connection to the off-road cycleway through Dunmore swamp oak forest.
• The elimination of narrow winding alignments without overtaking opportunities.
• A new bridge over the railway line at Lindsay’s Lane eliminating use of the level crossing near Dunmore Station by light and heavy vehicles.
• Raised road levels at Dunmore matching the northbound section of the North Kiama Bypass.
• A southbound heavy vehicle parking area and inspection bay at the Nungarry rest area on the North Kiama Bypass.
