Track and Station Platform - 8.3m
Track, Station and Sidewalk outside of station - 10.3m
Broadway at Alder:
Sidewalk 2.3m
Bus / Parking Land 4.6m
Centre Lane 3.2m
Middle Lane 3.0 m
So if you wanted a sidewalk, station platform and a designated rightaway you would have this configuration:
Sidewalk / Platform / Track / Single Eastbound Lane / Single Westbound Lane / Track / Platform / Sidewalk.
So where there are stations there could be single lanes in either direction
Where there are no stations you could have 2 lanes.
There would also never be any parking anymore!

A missing piece of the Streetcar /Tram /LRT on Broadway puzzle is that the minor cross-streets would have to be blocked from making left-turns to or from Broadway. Major cross streets would need left-turn bays with advance-turn signals for vehicles leaving Broadway to prevent left-turning traffic from getting smacked by the driving-straight-through Streetcar /Tram /LRT.
A simple example: left-turn bays at Broadway / Oak so Broadway traffic can turn East-to-North or West-to-South. These left-turn bays are already there, but will have to be relocated further away from the Broadway centre line because the rail tracks will be using the two inside lanes exclusively. You can't have a train being blocked by someone waiting to make a left turn.
Same left-turn bays at Broadway / Cambie and Broadway / Main for East-to-North or West-to-South left-turning traffic.
All of the minor streets that cross Broadway (Laurel, Willow, Heather, Ash, Alberta, Columbia, Manitoba, Ontario) will have to be made right-turn only intersections because you can't have traffic making uncontrolled left turns in front of the trains when entering or leaving Broadway.
Some minor streets may have to be cut off from Broadway by building a coul-de-sac.
Yukon and Quebec may allow left turns onto Broadway, but left turns leaving Broadway may be disallowed.
Now repeat this for every intersection all the way west to UBC and east to Glen Dr (VCC) - some streets get cut off from Broadway with cul-de-sacs, some get right turn only restrictions and some get left-turn bays with advance lights.
Oh yes -- how do you herd pedestrians safely across the tracks at popular intersections like Willow and Heather (Vancouver General Hospital & related medical buildings are nearby). Does a sweet elderly lady with a walker get to push the crosswalk button and block the Streetcar /Tram /LRT so she can make it to her doctor's appointment on time?
