In time, the pressure on the bridge from the land that filled in the old bay, or Berzelii park, as it then was, became too much for the bridge to withstand. It was decided to also fill the bay on the east side of the bridge, towards present day Nybrokajen. As a consequence, Nybron ceased to exist.
But not entirely. One of the sturdy cast iron railings remained. It still stands, almost defiantly, along the east side of Berzelii park, separating the park from Nybroplan.
