Regarding A-Line:
Let's consider:
- B-Line is traffic-dedicated to LRT, because you need fast crosstown movement.
- A-Line (future extension) should be traffic-dedicated to LRT south of King to allow fast journeys between Mountain and downtown.
However, A-Line being mixed traffic north of Wilson, actually isn't too bad if that preserves practically everything on James -- trees, light standards, heritage. You'd just put up a cross wire across the existing light standards, and wire catenary right underneath -- practical utilization of existing road infrastructure without tearing up anything on James except the LRT. Even all the existing public artwork would stay. It's a tough compromise but it's the apparently best-possible outcomes preserving James, if there's no other feasible route. Certainly, you do have mixed feelings, but I clearly see it's the most street-heritage-preserving outcome if the LRT stays on James St N.
That big advantage needs to, at the very least, be acknowledged, even with mixed feelings.
It actually even keeps the door open to eventual pedestrianization of James. The trees/lights/arts/etc stay, the tracks get installed, simple crosswires between light poles.
So, if LRT runs on James, this was actually apparently one of the best possible outcomes for James St N: mixed-traffic -- the only way to fully preserve James St N north of Wilson. With the silver lining of potentially becoming LRT-dedicated by pedestrianization (after sufficient densification & gradual diversion of cars to other routes such as John St) once sufficient LRT ridership allows. It'd still be fast crosstown (east-west) and southwards (A-Line dedicated extension south), just slow through James St N north of Wilson.
Otherwise if you separate while keeping cars, you've just converted James St N back into an ugly 4-lane stroad (shades of the early 90s) by tearing down trees, ripping up the light standards, narrowing the sidewalks, just to let 2 car lanes and 2 LRT lanes co-exist. Ouch.
Personal opinion only. Not shared by the whole team of LRT advocates. But one needs to see this couild have been easily a lot worse for James. A LOT worse.
