Сколько мостов в Стокгольме?
Not until the 20th century, Stockholm was able to surpass the straits and bays surrounding the city. Half of the about 30 bridges in central Stockholm were built 1920–50, most of them during the 1930s. This development was due to increasing traffic loads caused by a fivefold increase of vehicles in the 1920s. At Slussen, passing ships caused stationary rows of trams several hundreds metres long. The situation was solved when a traffic committee in 1930 could present the so-called "clover-leaf solution" of engineer Gösta Lundborg and architect Tage William-Olsson inaugurated in 1935. The modernity of the solution put Stockholm in a state of rapture and impressed even Le Corbusier, who praised the scale of the construction and invited the world to follow the example of Stockholm.
