The graceful Woronora Bridge in southern Sydney helps link the southern most residential area of the city, the Sutherland Shire, with the western suburbs. The Woronora River is a tributary of the Georges River. The "line" down the middle of the second photo is not a fault, but a piece of fishing line caught in the casuarina tree by the river bank.
Can you see the suspended walkway under the bridge? There are impressive views from there, which I'll go back to visit another day!
If you're interested in the engineering of this bridge, see here. It was opened in February 2001.
