The original survey methods in North America mean that there are country and county roads every mile, running in a grid across pretty much the entirety of the settled portion of both the States and Canada. Blocking off a highway isn't actually that big of a deal, you can always take the farm roads around the blockade and pop back onto the highway later.
Only in the most populated parts of Southern Canada.
There's thousands of kilometers of TransCanada east-west infrastructure that is literally a single lane of highway traffic infrastructure with fuck all as detours.
