In the past and today, Istanbul has always been one of the most important cities in the world because of its historical, cultural and natural features. This fact has caused increase in population and great transportation problem since 1950s. To surmount the transportation problem, two bridges were built and a third one is being constructed on the Bosphorus. Although zone plans, which made in the 1960s, suggested the urban growth to east-west direction, each bridge created its own traffic and triggered urbanization to northward.
