I was just South of Montreal and saw what they do. I saw so many 50cc type scooters, electric scooters and a car lanes divided with a centre line for two way bike traffic.
If the city changed to Main & King to two way traffic that is 4 lanes and one left over for a divided bike lane or parking. if the parking option was used with a West bound parking lane on King and an East bound parking lane on Main.
As for the cross town bike lane there is one already but it is so far south (Lawrence), it is under utilized as it adds distance, but it runs from the RedHill to Gage and hooks onto bike lanes to the downtown.
I think that maybe one lane of bike traffic be dedicated for either Wilson, Cannon or Barton.
East bound on Wilson would connect on with the Plains road lane from Burlington and go all the way to Sherman.
Cannon should be the Bike lane goal as it is being resurfaced from Gage to Ottawa and could be painted as soon as the job is complete.
As the road is now closed the opening would soften the transition.
If you consider the Cannon\Brittannia Option you would have a link that would Join onto the RedHill bike path and bridge to the waterfront with minor change other than signage.
