The red lines I show on that map I posted is the right of way for those roads. In the early 90s, The Harbour Expressway and Thunder Bay expressway were supposed to be expanded to six lane controlled highways with interchanges, and the entirety of 11/17 was to be four lanes, divided between Dorion and Sunshine, with a new four lane divided and controlled highway between Thunder Bay and Shabaqua. In reality, only one of about 20 interchanges was built (that is, half build, as it still has a lighted intersection), only about 4% of 11/17 is four lanes, none of the network is 6 lanes, the highway between Shabaqua is two lanes ("Will be expanded to four in the future"
) and ends about 60km short of it's destination.
The funny thing is, that two lane highway cost more than the four lane would have because the government bungled it up so much. When the four laning is completed in the future, the highway could be as much as 400% overbudget. (Just like the hospital, which was four years late and 350 million more expensive than it was supposed to, and is not only falling apart but sinking.)
Generally: Infrastructure = (The rest of Canada > Ontario)
