You report (NCE 8 June) that Hammersmith Bridge is likely to remain closed for at least three months following the recent bomb incident. This seems a very long time given the localised (albeit significant) nature of the damage, and suggests that no great importance is placed on reopening the river crossing. I feel sure that, had this been a railway bridge, Railtrack would have carried out repairs sufficient to get traffic moving again within a couple of days or so. Perhaps such an easygoing approach to London's road traffic problems is something the new mayor will be taking an interest in.
