The widening of the existing bridge is for the start of the ramp off to Nose Hill Drive.
The twinned bridge over the CP Rail tracks is to accomodate the ramp distance of traffic entering Stoney southbound. That's why that bridge is being done now, instead of going ahead when the bridge over the river is going ahead.
The current bridge over the river has always been intended to be twinned eventually. It's two lanes each way with virtually no shoulders. This will become three lanes northbound with shoulders when the bridge is twinned. The earthwork for the twinned bridges was done with the initial bridge. I suspect the the twinned river bridge will be built once Stoney Trail continues further south than 16th Ave.
