"The covered expressway is an idea that Sophie Larochelle can get behind.
Her kitchen can get busy around dinnertime, but nothing compares to what is going on just steps from her home as cars and trucks rumble by." https://www.cbc.ca/news/canada/montreal/decarie-expressway-covered-1.5025880
https://upload.wikimedia.org/Autoroute_Decarie.jpg This is what
Vancouver wanted to avoid between the 1950s and 70s.
Indeed, something like Autoroute_15 and Interstate_5_in_Seattle would have meant that entire blocks would have been cleared from downtown Vancouver to the Fraser River to Richmond. Then a swath from downtown Vancouver to Burnaby, connecting to the Trans-Canada_Highway.
https://upload.wikimedia.org/British_Columbia_Highway_1_as_it_enters_Vancouver_from_Burnaby.jpg The irony is that the roads and streets in Vancouver could have been upgraded without having to build freeways in the city limits. Instead, an agenda to create bottlenecks and more congestion was established in Vancouver. Fortunately, Vancouver has no control over Burnaby and Richmond.
If Vancouver was somehow able to water-down the freeways in Montreal and Toronto, it would be a disaster of congestion. Especially making the subway stations smaller, causing much shorter trains.
Most major cities don't have a multi-generational agenda to continually water-down and thwart its infrastructure like
Vancouver does.
