When it was first opened on March19,1932, the bridge had two railway lines, two tram lines and four lanes for motor vehicles. There was also a walkway for pedestrians. In 1950 the tram lines became extra lanes for road traffic.
People can climb into one of the pylons for a view of the bridge and the harbour. Since 1999 groups of people are taken on climbs to the top of the arch.
