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
