It's $200 million for the initial cut and cover, and $300 million for interchange upgrades (if/when needed).
Without the tunnel, the estimate is $345 million in upgrades to improve alternate access. This doesn't take into account cost of upgrading existing roads when planned commercial development goes up along Country Hills and they find that these routes are becoming clogged up.
Of course, if they go "oh crap, we need a tunnel" in the future, the cost more than doubles.
Info doc. I think this is one of the recent ones.
