Given they've now banned pedestrians and cyclists from the bridge one can
only assume its gone beyond needing repair and has moved into dangerous
structure territory. I wonder what effect that'll have on river traffic
beneath if they're worry bits are going to fall off.

All River traffic has been prohibited.

Unlike the roads where diversions though inconvenient exist the
alternatives for river users are far less.

Fewer, perhaps. Just the Regents Canal route I suspect.

And the number of craft that are based on the Thames that can fit the Canal
Dimensions must be a fairly small percentage. At least as far as I know the
Boat Safety Certificate is now common between
CART and EA managed navigations, one time they differed a bit.

You would only want to do it doing for the sake of doing it but if you had
a suitable craft like an old ships lifeboat conversion and the
navigational skills accompanied by a suitable stomach it may be possible
to go Grand Union , Kennet and Avon ,Bristol Avon then around the Coast but
the type of person who would want to undertake such an adventure would
probably be doing it regardless of the bridge closure.
The specialised sea going barge type one of which featured the Actor
Timothy Spall going around the coast will fit the Grand Union but is just a
little too big for bits of the Kennet and Avon .
