Bridge technology changes, and bridges, along with everything else, have grown larger, higher and more elaborate.
The temporary span seen in the left foreground is being used to take down the old orange structure, half of which can still be seen.
The new Port Mann bridge is enormous. It has double the capacity of the old sixties vintage bridge, and at 65 metres, is one of the widest in the world. The bridge deck is high and broad, with ten lanes suspended from soaring cable towers and a thicket of white cables that meet overhead.
