To clarify, this won't be replacing any current roadway.
Barlow Trail south of the terminal is going to be closed once construction begins and the new runway will be built where Barlow currently sits. Once this happens, everyone will have to access the airport from the north.
The tunnel will be an extension of Airport Trail under the new runway, connecting to the northern edge of Saddle Ridge, and communities that don't exist yet.
Without the tunnel, people in those communities would have to go either north to Country Hills Blvd or south to McKnight Blvd to get to the Deerfoot, or anywhere west of the airport (which is what they currently have to do anyway). With the tunnel, they'll be able to split the difference and use Airport Trail (and have a quicker route to the airport).
