So Hammersmith is very much a one-off. That doesn't mean that other
structures don't have problems of their own, but the design and
subsequent operation and maintenance practice related to the
Hammersmith flyover seems to have combined in a way that could only
end in tears.

No matter. There's little doubt that the prospect of all those Olympic
athletes and officials setting out in their limousines from Heathrow,
only to encounter the traffic jams that those of us who live in the area
currently suffer, will ensure that it is all fixed in record time.
