Well, you've answered your own question: a properly designed, 6 lane arterial road could possibly accomodate a bicycle lane, ESPECIALLY IN A CITY THAT HAS BEAUTIFUL WEATHER 12 MONTHS OF THE YEAR.
Look no further than Birchmount, which recently went from 4 lanes to 2 south of St. Clair so that a bicycle lane could be added.
I happened along there Sunday around 2:00 - sunny, beautiful day: one bicycle, dozens of cars in a line. Such is progress in this city.
Pity all the workers in those factories and warehouses in the area that now have to struggle with ONE lane in each direction. How a city of 3 million considers a 2 lane arterial road acceptable in this day and age is beyond me. Owen Sound has more capacity on its streets!
I understand the plight of cyclists, but it is outrageous that wholly inadquate lane capacity is taken away so that a few bicycles can trundle down those roads in peace. Even on Sherbourne St. where I live, autos vastly outnumber the bicycles on a gorgeous day, let alone the winter. Yet still they keep building 40 story condos and soon Wellesley will be constricted to a single lane.
