IMAGINE a version of New York's famous High Line, an elevated cycle and walkway, running through the centre of Sydney.

When the NSW government announced last month it would remove the network as soon as possible, many sighed with relief. With public debate now turning to what should happen to the structure once dismantled, David Vago has drawn up a plan to turn the tracks into an elevated boardwalk and cycleway.

He said pulling down the tonnes of steel infrastructure would be a missed opportunity - and a waste of money.
