Indeed.
That map of the sinkholes WRT the TCH at Oxford is truly frightening. It makes you wonder if they shouldn't be actively reconsidering realigning the road around Oxford.
But you're quite right, the other risk to the TCH at the Isthmus of Chignecto is equally as frightening. The current dykes protecting the Tantramar Marsh at the isthmus are very old, increasingly fragile, and at increasing risk of getting overtopped by flooding events. This almost happened once a couple of years ago during a storm and the only thing protecting the TCH from getting flooded (or washed out) was the CN Rail embankment (which wasn't really designed as being a flood control structure when it was built). It was a near catastrophe.
The TCH at the Tantramar Marsh is really the only practical route from Nova Scotia (and Newfoundland) to the ROC. If it were ever to wash out in a major flood, it would cripple the Maritime economy.
And meanwhile the governments do nothing, choosing instead to gaze at their navels and blame each other as to whose responsibility it would be to pay for a fix.
