Fair enough, I was just asking. Also the comments about Health & Safety are well considered.Rebuilding a Bridge (and a big one st that) is a non trivial task. There will be site compounds to erect, road closures to arrange, utilities to move, lay down areas to clear, environmentsl mitigation measure to install, line closures to arrange (timescale for major closures: minimum 14 months, maximum 26 months). Then when it is done, the site compounds / lay down areas have to be cleared, and restored ready for future use. Only then is it finished.
It seems to me that even with all these considerations that it still seems to be a long time.
But as a printer I accept the view and comments of those who are more experienced than me in these matters.
