That has affected my last London Relative who often took an exercise walk
over it and back around over Barnes Bridge, he doesn’t expect to recommence
that in his lifetime.
He is of the age to remember and mentioned that in WW2 the authorities
reasonably quickly erected a couple of temporary bridges just in case
bombing destroyed a bridge, they did not wait for it to happen . AFAIK
fortunately were never needed and removed around 1947.
They have reached the stage of being almost forgotten.
