Three!

Fantastic walking day with friends.  We caught the train to Inverkeithing, and then walked back down to South Queensferry for a lengthy pub lunch.  The walking route took us along The Fife Coastal Path, into North Queensferry, across a pretty windy and cold road bridge, and then down into South Queensferry-all very scenic.  I was most impressed with the coastal section before the bridge.
The photo includes the rail bridge, the original Forth Road Bridge and the beautifully designed new road bridge.
