New Westminster, BC

Unfortunately, the little river city of New+Westminster never saw itself as having the same potential as Portland, Oregon. NW eventually went from being a backwater BC capital to becoming part of the Greater Vancouver Metropolitan Area. Unlike Portland, it has always been reluctant towards having wide train & road bridges.

The SkyBridge should have been multimodal like the fantastic Tilikum+Crossing in Portland.

The Steel Bridge in Portland vs. the New Westminster Rail Bridge

The current Steel_Bridge opened in 1912 with tremendous capacity well over a century later. Perhaps the designers looked at the narrow New Westminster Rail Bridge & decided to avoid the BC bottleneck approach to things. 

Upper: 2 outer lanes for general traffic, 2 inner lanes solely for MAX Light Rail, and sidewalks on both sides
Lower: Union Pacific Railroad (incl. Amtrak toward Eugene) and walkway.

Unlike Portland, NW never seemed to ever want to become a big bustling river city, just another provincial backwater. There was a time in the 1800s when NW could have acquired what would eventually become known as the Tri-Cities. However, that wouldn't fit within its backwater BC mentality. 

Indeed, to this day, the former BC capital & Victoria are quite small when compared to Edmonton, Regina, Winnipeg & Q. City. However, since little NW is in the middle of Greater_Vancouver, it has been gradually encouraged to take on more big city attributes.
