Princes Highway) in 1989. Albion Park Rail Bypass At the southern end, the Princes Motorway was extended to Oak Flats via a 9.8 km bypass of Albion Park Rail. The bypass completed the 'missing link' in the four-lane road between Sydney and Berry (currently being extended to Bomaderry). The bypass was constructed on a corridor which was identified by the Roads and Traffic Authority in a study in the mid 1990s. In 2013, Roads and Maritime Services (successor to the RTA) confirmed the reserved corridor to be suitable for the bypass. The bypass was completed on 9 October 2021, several months ahead of schedule. The section of the bypass between Yallah and the Illawarra Highway (Terry Street) interchange was opened to traffic in May 2021. The northbound carriageway of the remainder of the bypass (ie north from the New Lake Entrance Road interchange to the Illawarra Highway interchange) opened to traffic on 7 August 2021. The remainder of the southbound carriageway was opened to traffic on 9 October 2021, thereby completing the bypass. Exits and interchanges Proposed extensions Northern extension The County of Cumberland planning scheme of 1948 outlined an F6 extension from the current-day end-point at Waterfall. As such, an F6 corridor was set aside that passes through the Royal National Park from Waterfall to Campbell Road in St Peters. The land reservation tract currently passes through the suburbs of Loftus, Kirrawee, Gymea, Miranda, Taren Point, Sandringham, Sans Souci, Ramsgate, Monterey, Kogarah, Brighton-Le-Sands, Rockdale, Banksia, Arncliffe, Kyeemagh and Tempe. Of the proposed extension, only the six-lane Captain Cook Bridge and a short connecting section of Taren Point Road to the south have been built. Establishment of the bridge section of the F6 extension began in 1962, expedited to replace the ferry service that had operated from Taren Point to Sans Souci since 1916. Captain Cook Bridge was opened in May 1965. In the original plan, the F6 would connect to the Western Distributor. Then, in August 1977, premier Neville Wran cancelled the inner section of the F6 link, which at the time had an estimated construction cost of $96 million. At the same time, Wran announced that the inner section reservation would be sold off and the proposed extension would instead terminate at St Peters, a medium density industrial suburb. Prior to the 2007 federal election, the Liberal–Nationals (Coalition) government promised to allocate $20 million towards planning for the
