Hollis is likely too narrow to do two way traffic for a streetcar - why not inbound along Barrington and Hollis with outbound being Lower Water Street and then back to Barrington?
I have a couple concerns about putting a streetcar on Spring Garden Road. First is for the businesses - how would deliveries be handled? I'm assuming off peak and there would have to be a schedule. So long as they are accommodated, then I'm fine with it. Second is the turn from SGR to Barrington Street. That is a tight corner, even for articulated buses. So if we use something like
this, I don't know if it could make the turn. But if we use something like
this it might be okay.
One of my reasons for proposing a streetcar network like I did, was to use it as a mechanism for growth and change. I think we need to look at areas like Agricola, Windsor, Quinpool, Robie and around the Hydrostone as a way of encouraging future growth and change. Same with Highfield Park, Shannon Park, North Dartmouth and Wallace Heights.
Another thing I would mention is that if a road has a landscaped median, this may be an opportunity to use the median for the streetcars. I've been reading that there are ways to transplant mature trees (and many of the trees would be) - why not relocate them to Point Plesant Park and then put in a streetcar?
