When it comes to landmarks, bridges are a special category. They are a practical and sometimes spectacular symbol of unity - the joining of two sides previously separated. San Francisco's Golden Gate Bridge is one of the worlds' most famous. It connects the northern tip of the San Francisco peninsula to Marin County as part of US highway 101.
