[You Need a Thneed]

A n/s tunnel makes sense for airport access. But it doesn't serve the main purpose of the tunnel, which is to provide skeletal road access between Deerfoot and Stoney, allowing the area to be developed.

Also, traffic studies showed that with Airport Trail complete, Metis won't be required to be a freeway, and in fact, traffic in the area will work better without Metis being a freeway. The classification of Metis has already been changed, so don't ever expect Metis to be a full freeway. It will likely get interchanges at 64th and Airport Trail, but 80th, CHB, and 128th probably will never be grade separated. As well, new intersections may be put in at 72nd Ave, 88th Ave, & 104th Ave.
