All that remains of Port Melbourne's Centenary Bridge is this pylon, still in situ.
Even if you are only a thirty years old Melburnian, you probably can remember that bridge on the beach road at Port Melbourne.
In spite of the nice remaining pylon, it was ugly and dividing and I would go so far as calling it a monstrosity.
The area is so much nicer now, as is Flinders Street without the King Street overpass. Predictions of the end of Melbourne should it be demolished proved to not happen.
The second photo should be large enough for you to read of this history of the Centenary Bridge, should you so wish.
I just had a look at google images and it seems it was so ugly, no one ever took a photo of it.
