I think the only solution is to have a sturdy steel beam, painted in
luminous paint, a few metres before the bridge (and obviously mounted so
that, even if hit, no force is transferred to the bridge parapets). The
beam might be a few cm below the bridge, but there might also be a
hanging
fringe below that so it's right in the driver's eye line.
Well he failed to spot the pretty obvious warning signs on the bridge so I
doubt this particular Einstein would have seen a painted beam either.
Are we sure he ignored the signs, rather than forgot (or didn't properly
know) the height of his vehicle. Forgetting what you are driving is just
about the only reason one of the fairly regular double-decker bus bashes
happens.
It's a shipping container that hit the bridge, so the driver may well have
been caught out by the size of that.
Another solution for fixed height vehicles would be to mandate the fitting
of warning devices to the vehicles themsleves; I saw a very effective radar
system in use on a coach some years ago. However, this would be harder to
put into practise for vehicles like this one that can carry a variable
height load.
