This is a project called the Seven Bridges Walk which is the route of a charity event held each October. Participants walk what is basically the Sydney inner harbour foreshore.
It begins near Circular Quay and follows the shore line around the historic "Rocks" area and onto the "seven bridges" which cross various tributory harbour waterways. They are the
Pyrmont Bridge, Anzac Bridge, Iron Cove Bridge, Gladesville Bridge, Tarban Creek Bridge, Fig Tree Bridge and (finally) the Sydney Harbour Bridge, bringing walkers back to where
they began. A map may be found at http://www.7bridgeswalk.com.au/pages/event-maps.php . My friend Tony and I followed the route as a private exercise taking pictures as we went.
We completed the task in three stages (three hours, three and a half hours and three and a half hours) a total of 10 hours of walking. The route is a useful addition to the "Walking
Coastal Sydney" route (shown in other galleries), which only covers the outer harbour.
