It is said that Berlin has more bridges than Venice. Actually the city at the Spree river has almost 1000 bridges from several stylistic eras.
Berlin’s double-decker bridge the Oberbaumbrücke (1895) - Oberbaum Bridge - links the two Berlin districts of Kreuzberg and Friedrichshain separated by the River Spree. Traffic runs on the lower part and trains on the second level. It was built on the site of a previous timber bridge built in 1724 when the construction of an elevated railway required a reinforced structure. The result was a seven-arched concrete bridge with a granite and brickwork façade. It is distinctive architecturally because of its mock medieval turrets – which recall the function of toll bridges and arches.
