Broadway is one of those places that needs Skytrain and not LRT. it is a major transit and road connection and it will only grow and LRT, like others have said, is just an expensive bus with
slightly more capacity. and we could get more capacity with buses if we had those bi-articulated ones. LRT is out of the question i think for Broadway.
way too many cross streets and you cant take away 2 lanes from that road. way too much traffic and way too little parking for all the businesses. with a lack of E/W streets in Vancouver as it is you cant take even more away. with a Skytrain i would be willing to bet cars would get off the street since commute times would be so much better, i
would switch for Skytrain

. with LRT

i know i certainly would
not switch over.
if it is Skytrain versus grade-separated LRT, is grade-separated LRT really much cheaper? i don't know the facts on that so i cant really say. though i'd imagine the costs would be somewhat similar.
should it go all the way to UBC?

its debatable but i think it should go all the way. get it done with so in 30 years we arent talking about "why would they stop it there?" and then have to pay more billions on top of what the full cost to UBC would be now. in the long term is it just cheaper to go all the way. we have a lack of forward thinking in the city/province and it is the reason we have so many transit/other infrastructure problems now. lack of future thinking of our former mayors/premiers. do we really want to continue this kind of thinking?
i do think UBC should pay a percentage of their parts. not 100% but they should cover some of it for sure.
*when i refer to LRT i mean surface, unless otherwise stated.
