I believe the ND Clifton Lea study recommended tunneling only as early as just before Centre Street though.
EDIT- Andasen beat me to it.

So, during the study, they sat down and calculated that it would be better to make the train cross both directions of busy Macleod Trail, and then have the entrance to the tunnel be in what is now the middle of 10 Ave SW, compared to using the ~200m (of empty land) between 4 St SE and the SLRT tunnel to get far enough underground?
There are many, many places on the LRT that don't function well because planners were cheap and short sighted, including nearly every major road crossing. I would be surprised if the accidents, delays, and maintenance weren't more expensive overall than it would have been to build a little bit better.
Of course, since we can't seem to afford to do a detailed design for, let alone build, any new LRT lines, we have a very long time to debate these questions...
