Had to be built?

You have obviously never been on it or near it.

A perfectly serviceable, existing route on Country Hills Blvd,  a mere 1.5  km to the north. 


A $480 million boondoggle. 

When originally proposed it was to avoid having to close the Barlow Trail  which was then the main access the airport, prior to the now universally used, and far shorter Deerfoot Trail  and Country Hills Blvd accesses. And the Barlow access is now closed anyways.

yeah, you really know this issue.
