Because the North Shore is NIMBY central.
The Evergreen Line has and will face far less opposition then the Broadway Corridor (especially since it will be tunnelled and Cambie memories are still fresh). Look at how much nonsense has already gone to supporting LRT over ALRT/Metro on such a busy essential corridor.
Also the Evergreen Line is far ahead in planning and alignment then the Broadway corridor and has significant Federal and Provincial funding already allocated for it. To stop this project now, at this stage, would be incredibly silly (not to mention all the money that would already have been wasted on all the studies/open houses/designs etc...).
Also the North East sector is rapidly growing and actually has very dense neighbourhoods, major retail/commercial centres and major transit hubs along its chosen route.
The amount of high-rises built along where this line will go in Port Moody and Coquitlam over the past 5 years is amazing.
Do I believe that the Broadway corridor deserves rapid transit more then anywhere else in our region, yes, am i angry this line is being built first? No, simply because these communities have been campaigning for it for decades, have been mending their urban designs over the past 10 years anticipating such a line, and are essentially in full support of the project.
Metro-Vancouver already has far to many splits in ints pro-mass transit groups: Rail for the valley, LRT over skytrain, etc... The last thing we need is another split among the skytrain supporters.
Yes the Broadway Corridor should have been built first, but in all honesty, the tri-cities community was able to get their shit together quicker and stronger, so they now deserve it first.
