Bridges can symbolize man's desire to span the world, to bring people closer together and to access further territories.
This series looks at the significance of bridges as icons, as a means of connecting communities - or delineating separateness.
Part One - Brooklyn Bridge
Brooklyn Bridge is a "blank canvas upon which people project their ideas", and this programme creates a portrait of this iconic structure through the experiences, thoughts and imaginations of its visitors.
We hear from a carpenter responsible for the maintenance of the boardwalk whose childhood memories are wrapped up in the bridge's cables and a homeless veteran contemplating his future as he sits on the bridge.
Italian artist Joseph Stella depicted the bridge as a metaphor for the immigrant experience in America.
What does the bridge mean to people who cross it today?
