I think choosing the Wharncliffe (1b) route would be better for the city downtown core integrity and the pedestrian culture of walking on Richmond st.. Londoners identify Richmond st. with its downtown very much.
If you deface Richmond st., might as well crap on the whole downtown fascia too.
Having buses zoom in and out of Richmond could be an eye sore and too industrial feeling for a downtown. Richmond st. reminds me of Younge St. in Toronto. If you add painted bus lanes and tunnels on Richmond, it would look like a highway. Do you think that the painted bus lanes would last very long with our winters and salt on the roads? It would look very bad worn out. Look at Sarnia road, the fresh painted bus only lanes are already worn out.
Also wide streets are not very pedestrian friendly they remind us of highways and fast roads. Highways should not go thru downtown, but on the edges of it.
Downtown needs to have patios where people could enjoy the nice cheerful atmosphere that should not have noise pollution by loud buses.
What happens to the rapid transit through Richmond when we have so many festivals at Victoria park? Would the massive crowds disrupts the flow of buses? Would the noise of the rapid transit disrupt the festival gatherings and enjoyment?
Why does not New York city put a highway or fast BRT through their Central Park? Come on guys lets not deface our downtown for the sake of a transit route. Choose Wharncliffe and you still keep the integrity of our city.
Take Ottawa for example, their Rapid Transit does not go through the middle of downtown. It goes on the edges of it.
