I had trouble gathering information about the bridge on the postcard, which might be the Bonn Rhine Bridge. But after spending almost my whole shift, I found some limited (and sometimes confusing) information about the bridge's history. I just hope that the one being discussed on my source is the Bonn Rhine Bridge on the postcard. So anyone from Germany? I need confirmation for this one.
Below is the picture of the Bonn Rhine Bridge pre-WWII.

What happened during the Second World War is that Hitler had decreed that no bridges over the Rhine would be captured intact by the Allies and preparations were made to destroy the bridge to prevent capture. The Bonn Brdige was blown at 9:15 P.M., March 8, 1945, by a Captain of the 6th (German) Engineer Regiment (later captured by the First Division), who had not slept for three days worrying over whether he would be able to blow the bridge at precisely the right moment.
Here's some description on the new bridge: RHINE BRIDGE, COLOGNE-DEUTZ (1946-47)
* Combined road-streetcar bridge.
* First slender steel box girder replacing a chain suspension bridge destroyed during World War II.
* Spans: 132.1-184.5-120.7 meters, girder depth at piers 7.8 meters and at center of midspan 3.3 meters, corresponding to slenderness ratios of 1:24 and 1:56.
* Orthotropic deck with reinforced concrete wearing layer.
* Erection in large elements with heavy lifting equipment.
Too bad the pre-WW2 bridge is much more elegant!
