An 8 lane section of freeway, but with 2 sets of tracks in the middle. https://upload.wikimedia.org/wikipedia/commons/6/6f/Mitchell_Freeway_147_N_Walter_morning_peak.jpg Once again, Perth, WA gets it right and BC gets it wrong.
https://www2.gov.bc.ca/gov/content/transportation-projects/fraser-valley-highway1 Instead of building an 8-10 lane freeway with at least 2 tracks in the middle, BC takes the half-assed approach, again.
https://vancouver.citynews.ca/2024/05/23/langley-hwy-1-summer-expansion Just like not desiging the Canada Line stations or any of the other SkyTrain stations, to not be able to accomodate 8-10 car trains, BC keeps dropping the ball.
People just don't understand that there has been a multigenerational agenda to hold BC back. Keep everything small & backwards. If BC had been allowed to really grow back in the 1960s & 70s, that would have meant more non-white people moving into a thriving region. Then even more restrictions were established in the 1980s & 90s, as the city councils & provincial government was predominantly of European ancestry. The British colonial mentality went right through the 20th century. Thus, it took a long time for BC to really accept international diversity. You have to build up the infrastructure for everyone, instead of refusing to do so.
Despite there being more diversity in various parts of BC over the past few decades, so many of the restrictions have remained. Vancouver has been trapped in a gordian knot of restrictions that hold it back. Victoria is nowhere as big as Quebec City, Winnipeg or especially Edmonton.
The one card left, is that someday Canada might have to say that it has to keep people out, because it's good for the environment. Meanwhile, several other countries with less land area are able to properly build up the infrastructure of their cities.
Surrey like Burnaby, isn't under the excessive Vancouver restrictions, so they will have taller buildings & some wider highways. Unfortunately, not longer trains, but that must eventually be changed. Short trains & narrow bridges has been a strong symbolic way of BC refusing to build up proper size infrastructure. Then Vancouver, NW & Victoria keep trying to hold back their growth.
