Bwa ha ha ha. Anchorage is nowhere CLOSE to built out. There's a ton of land inside that city that's developable. Right now it's far too low-density for a city, anyway, never mind the available land. I do know that the existing highways can jam up during rush hour, but I'd bet that's due to not having a continuous freeway (bypass?) connecting 1 and 3 more than inadequate capacity entering Anchorage. This is definitely a boondoggle project.
