When first proposed in 1951, the F6 Southern Expressway was planned to link Sydney to the third-biggest city in NSW, Wollongong. It would have started at a massive interchange in the inner-city suburb of Ultimo, head south through the dense suburbia of Southern Sydney, then through the Royal National Park, before extending all the way down south to Wollongong.
But only half the freeway was ever built. The freeway, now the M1 Princes Motorway, starts in Wollongong but ends 50 km south of Sydney, in the suburb of Waterfall. Why was the freeway never extended to Sydney? Find out in this video, and follow me as I trace out the expressway's planned route through southern Sydney, and explore all the hints scattered across the area that a freeway was ever going to run through the area. I'll also explore the under-construction M6 Motoway project, which is finally seeing the Southern Expressway be constructed...in a tunnel...completely different to what was intended by city planners 70 years ago.
