It is understood to be the first time a structure has been given such an honour, usually reserved for famous faces and extraordinary youngsters. The government said it was in recognition of the outstanding history of the 121-year-old rail bridge.
In an entirely unrelated announcement we understand from a BBC insider that former Royal Bank of Scotland boss Fred Goodwin has today had his Blue Peter badge removed. Mr Goodwin who was awarded the badge, ironically for painting a very pretty picture of another famous Scottish landmark, had it removed when it was discovered that the paint he'd used was not his after all.
The removal of a Blue Peter Badge is a highly unusual occurence and means that the holder will no longer have free access to a large number of Blue Peter Attractions.
