isn31c, I can see where you are coming from. The built landscape of most countries has the reminders of the past strewn across it, and I always have a slight chill on the A74(M) as I pass Lockerbie.
I feel it is good the remains of the old Tay Bridge could not be removed and are left, an unintentional reminder of that tragedy. Also that a similar design was being drawn up for the Forth Railway Bridge. The events of that night meant a completely new design from new engineers was needed.
Talking of the bridges, I do find crossing the Tay Road Bridge from Fife to Dundee is a very interesting vista because Dundee looms on the horizon. Sometimes it is difficult to remember that Fife, like the Black Isle north of Inverness, were effectively islands until relatively recently in how to get there. There is still the feeling both outwith and within Fife that Fife is somehow different to the rest of Scotland in a way the island areas are.
