I would love if they could figure out a way to keep the trees in the International Village.
I put a bit of thought into some potential improvements to the alignment, and I think this may be a good one which may actually save costs or at least be generally comparable:
Orange = Existing Alignment, including the orange hatched area which will be the MSF.
Red = new grade separated alignment
Basically instead of a huge bridge over the 403 and Cathedral Park, as well as rebuilding the Longwood Road bridge, it would have a smaller bridge starting west of Longwood Road. a new underpass underneath Longwood road with a grade seperated stop better serving the McMaster Innovation Park would then replace the currently planned Longwood Rd Station, before the line ran along the 403 to an underpass underneath Main Street. Finally, it would run along the CP corridor beside Cathedral Park instead of through it, before rising and meeting King St at grade like currently planned.
There is probably a similar amount of structure, if not less structure, involved, and it would allow the LRT to dodge 3 stoplights it'll have to navigate on it's current alignment. Would make travel times on the core segment of the LRT, between McMaster and Downtown, much quicker. Plus the connecting track to the MSF would be shorter, runing behind the McMaster Innovation Park instead, and allowing the Longwood Rd bridge to not have to be completely rebuilt to support LRT tracks.
