Thank you Rick Sinnott.  Note how many people ignore your pointing out that according to DOT since 1996 there were only two vehicle accident deaths in that area, both due to inattentive driving.   
There was the old mistaken highway design theory that "flatter, wider, faster" was safer, but that has been debunked for anything but freeways (where there is nothing to look at but ugly concrete).  The way you make a scenic road safer is to slow it down.  
But then we're not talking about saving lives, are we?  We're talking about money for contractors.  Why can't we have them work on something useful, like rebuilding our failing bridges?
Locals who want to commute from Girdwood need to allow themselves an extra 20 minutes, turn off the d&*m phone and DRIVE.
