Mr. Sinnott, if there are ways we can help change the DOT's/Fed's minds, would you let us know?  As a frequent motorist on this stretch of highway, I would submit that putting a four-lane divided highway between Anchorage and Girdwood would still not solve the problem (accidents/fatalities).  It isn't the fault of road design that is the major culprit here.  It's human error, for the most part.  

Reduce the speed limit for the Windy section and shave a bit off the northern corner to increase visibility and you have a lot less intrusive solution.  No, you don't get the fancy 4-lane highway with parking for viewing the Dall sheep that frequently graze on the mountainside; however, you do get traffic moving more safely.  (DOT admits the construction will scare away the sheep for the duration of the project, and there's no guarantee the sheep would return.)

Spend that enormous amount of money on other road projects that benefit more Alaskans.  Preserve what precious views we do have.
