TCH/Yellowhead/AB16 at the intersection with AB47. The westbound lanes are the original highway surveyed in 1960 and the intersection was at grade. The eastbound lanes were surveyed in 1985, twinning the highway, hence the overpass.

I remember that stretch of highway quite well, last time I drove it (starting in Vancouver, heading to Edmonton). Really an unusual stretch. For a few moments, I was thinking "finally, a proper freeway", and then you'd get right back to at-grade intersections. Then you'd get something like this, where they decided to do both at one interchange. Really unlike anything I've experienced regularly in BC or WA (both places have very few divided highways like those in Alberta).

The reason would probably be the UFA truck stop, and other businesses and houses, north of the WB lanes. The existing exit is just for a service road, which would make things difficult to have both highway traffic and slow moving vehicles if it were a highway exit. I don't know if the traffic count would warrant an underpass there.
