What happened to Montreal's blue brick backroads?

    Up until the mid-sixties laneways near Old Montreal were covered in blue bricks at a time when alleyways were routinely used as legitimate roadways.
   According to Janet Coutts, who around 1963 lived in a seven-room $75-per month cold water flat on Notre Dame near Montcalm, taxi drivers would ferry her home from her workplace on Bishop, taking laneways for much of the route in order to avoid red lights.
   The laneways were eventually paved but and somebody appears to have purchased the blue bricks which were quite beautiful, she notes.
