Hamilton never needed all those lanes of traffic. New York City's density is many times higher and they have PLENTY of roads that are 3 lanes or less. Its not really a matter of population, its a matter of shifting from cars to more efficient modes of transportation AND because we need room on the roads (vast amounts of public space) for other activities and walking. On most sidewalks in Hamilton there isn't even enough width for two people to pass two other people coming the opposite way.
