Here is another picture. you can see the church in the background. The right side is the road to the houses, and on the left is the speed-way with 2x2 lanes. It was (still) crazy back then.
EDIT: I was corrected. Its not. It is the substitute road.
Here is a recent picture looking from the other direction. Again the church now on the left. It was a crazy project but it was well received by the Altstadt/Oldtown.
In the German Wikipedia you can find another nice picture of the Rhine-Bank (Rhein-Ufer). It shows the Steps to the Rhine in 1900 - before the asphalt rolled over all that land. Notice the church and Tower in the back. And today.
