"In the 1980s British Rail claimed Ribblehead viaduct was going to fall down within 5 years unless about £5 million was spent on it - and that as a result the Settle and Carlisle line would have to be closed. Then the Minister of Transport told BR they couldn't close the line, BR spent about £250,000 on the viaduct, and surprise! - it's still there."
