Looking on Google Earth, it might be possible to cross the river via
the weir at Hampton Court as well. The entry for Walton Bridge is not
that clear. It is still possible to cross by vehicle there, a new
bridge having been constructed. This is a temporary structure, though
how temporary until the new bridge is built is anyone's guess. That
saga has been going on for years. The old bridge is still in place as a
footbridge. Its an original Bailey Bridge which I believe once
attracted interest from the Imperial War Museum.

Walton Bridge is fully open.

It is physically possible to cross at Hampton Court Weir over a access
walkway above the weir, but this is not open to the public.
