The 4 lane Louise_Bridge has a 2 track counterpart.

The Louise+Bridge & its LRT bridge is a good example of how a road & passenger rail corridor can work well.
The 4 lane Cushing+Bridge wasn't widened for buses, so the next best thing was done. A 2 lane bus bridge was built next to the Cushing+Bridge. What is easy & straightforward for Calgary to do seems to be very difficult for Vancouver & BC to achieve. Several bridges in Greater Vancouver should have bus & bike bridges built next to them.
