Because the up/down Island traffic was overwhelming the little towns along the original highway to the point where the local kids took their lives in their hands in order to cross the street.
That upgrade was about 20 years too late as it was, but for places like Bowser, Union Bay, Royston, etc ... residents have got their little towns back minus every single car going up or down the island.
Fun fact ... if your not in any sort of rush, 19A is still a much nicer drive up island than 19 is.
+2 - unless you're rushing for an appointment with God, or are going from points A to B as a result of a true family or other emergency, I've never really understood the appeal of the "inland route", although I understand perfectly why it was constructed. I just personally never opt for it given the choice.
Admittedly I'll be the first to concede that I am not at all a 'need for speed' freak - I'm perfectly happy motoring along the infinitely more scenic eastern route at 80 kph plus(ish) as opposed to the 120kph ++++++ I've routinely experienced on 19 when I have done it, the last time being probably more than five years ago - but really you cannot compare the "new" highway with the quaint appeal of 19A, the 'Oceanside Route'.
Quite aside from the fact the latter affords a stunning water vista throughout compared to really nothing on "19" other than endless kilometers of grass median, you also have an opportunity to pit-stop at any one of a number of beaches or beach-side camp grounds and quaint cafes as well as see something of what the island life was years ago in picturesque towns like Union Bay and Bowser.
One of the very best water-side pub/bar/cafe's on the entire east side of the island for example is at French Creek/marina - but you'd never see or have a chance to check it out roaring along on 19.
As to why the Inland Route apparently or seems in the eyes of the public to have higher urgency "to get it done" from the perspective of whatever the government of the day was, here is a fascinating link to a document from the Campbell River museum that outlines some interesting developments that clearly pushed the process (for a new route) along. Lots of interesting 'back room' material here. And not only that check out the image of the "original" island highway and imagine clearing those trees to construct that road!
