The planned Langstaff link over the CN yard is a very interesting (and expensive) project which would completely change how traffic is distributed in Vaughan.. would take a ton of pressure off of 7 through VMC, particularly in terms of truck traffic.
I'm almost surprised to not see Green Lane identified for widening, my understanding is that it's already a very busy road and will see a lot of growth along it in the coming decades.
Agreed on BRT being the better option for YR for now, but I could *maybe* see an extension to Major Mack in Vaughan if it could be elevated to keep costs down. Jane certainly has the space for it.
