Alta seems good as-is as well. While a freeway connection is a plus for justifying upgrading a road from tertiary to secondary, it's not necessarily required for secondary classification. Alta in its own merits should qualify for being a secondary road in that it provides a single straight shot route from Summerlin West to Downtown. And with its physical construction and AADT, it also slots right between a typical grid collector road you would see tagged as tertiary and a major primary thoroughfare like Charleston. Summerlin West may not be the perfect contender for a primary route (at least for the time being, over the coming years when it gets more built-up that could change), but it's still a major neighborhood seeing more and more traffic using these arterial roads by the day as it continues to grow.
