So why have the supports of the old bridge been left behind?

In case they were needed for future railway development? In fact the
easternmost piers are going to be used for the Blackfriars station widening
work duringThameslink 20??

Another possibility is that if they were in good nick, they may have been
left to provide part of the upstream 'cu****er' for the current bridge's
piers. A civil engineer might be able to confirm that, I shoud think one
will be along anytime...
