If you saw last Sunday's post, you 'll know that for a short while I'll be posting bridges from an exhibit currently taking place on Belgrade's pedestrian street, Knez Mihailova.
If I am not mistaken (and yes, it's been known to happen), this must be the bridge built by the Germans after they destroyed King Alexander 1st's bridge, built in 1934 and destroyed in 1941. The post card reads "Zemun", which at the time extended along the Sava River to include the Old Fairgrounds, which was turned into a concentration camp. This bridge was undoubtedly used to allegedly transport Jews to a new site on the other side of Belgrade, but if you check this link, you'll see what really happened as they crossed this bridge and part of the city.
King Alexander's Bridge was rebuilt after the war and later replaced by the present-day Branko's Bridge.
See other bridges at Louis La Vache's SUNDAY BRIDGES.
