Very. No space left, positioning of harbor basins and river left very little space, there was no unused space on the island it landed on and the existing bridge was too low so it had to go anyway. The latter is probably the main the old stuff is gone. They raised it by 2.5m in the process to fit modern river-ships which are a backbone in moving the goods landed in Hamburgs harbor to where they are needed. With most bridges destroyed, the Elbe was cleared for a decent usable hight once the worst war-damage was dealt with.
