Actual crossover of 162 Ave is about here - see PDF from City
http://www.calgary.ca/Transportation/TI/Documents/Road-projects/macleod-162ave/macleod-162ave-completed-diverging-diamond-interchange-fall-2017.pdf
Assuming PDF is accurate (& why not?) crossover is west of west end of bridge by a distance almost exactly equal to the length of the bridge (taken at NW corner of S bridge)
Sun Valley crossover is similarly placed relative to E end of bridge.
