When I was young I had a book about the age of steam. One memorable piece in the book was about the Titanic; the other was about the Britannia Bridge, Robert Stephenson's 1826 marvel that was so unforgivably destroyed by fire in 1970.
But the magnificent stone lions are still sitting on their massive plinths. They were the whole reason for me cycling all the way from Chester.
That the bridge was adapted to carry a road deck above the railway is of no special concern to me, except that in doing so they completely blocked the view of the lions to train passengers. They would have been a most splendid sight shortly before one's train ventured into the great iron tubes.
