Unless you have a GO train every 10-15 minute 7 days a week, you will see no decease in traffic on the QEW to Hamilton, let alone Toronto. Even widening will not do much for traffic.
You can get 8 lanes in between Confederation and 406 with a possibly 10 by shifting the service roads and it will require new overpasses for the 10 lane. A few bridges will have to be widened for 8/10 lanes.
Time to drop this need for HOV to the point you make it an transports only lane since they are moving goods costing more than that 2 - 4 person car.
The QEW from Toronto to Hurontario St is max 6 unless you remove the service road. Hurontario St to 403, it can be 8/10 lanes. Have to recheck, but you may get 10 lanes from 403 to the Skyway bridges. From St Catherine to Fort Erie, you can get 8 lanes in there. Will have to rebuilt the NF interchange for the extra lane(s).
Drum. Some interesting points. GO 15 minute service is a must, and a key, with more and faster service into the Niagara Region. HOV lanes vs TLO (Tranports Lane Only). Brilliant thought and why has it not occurred to the rest of the car centric world? Or maybe just myself. You would need a TLO from the 403/QEW split in Oakville to the 405. And then from K/W to past Oshawa on the 401 (or use the 407).
As for expansion. I get this to a point. Yesterday the QEW was a drag from the 403/QEW split, all they way through to the Freeman and then around to Red Hill. And it often is, and either direction, and any day of the week. And then into Hamilton and up the mountain on the 403, past the Linc, towards Brantford. So yes, more lanes should add capacity, but for how long? And at what cost?
The longer term keys are still better regional transport, and better built, better planned density and the ‘evil social upheaval’ of the 15 minute city, town, village…More frequent, fast, comfortable, connected GO rail and bus services, featuring rail lines, bus ways, light rail, separated bike lanes and trails, and changes in attitude about cars and big cars, and how we use them. And communities that are less reliant on cars for so many family activities.
it wail be really interesting to see the effects of the light rails lines in construction now in Toronto and Mississauga once fully functional. (as in when ever Crosstown opens? Followed by Finch and then the Hazel line) Could be quite transformative and maybe add impetus to more separation of existing streetcar trackage. One can hope.
Great post Drum; may have to go have another cappuccino while doodling on this one.
