I haven't heard of its being signed as a numbered route. It wasn't when I was out there last October, though the redesignation may've happened after I left town.
I'll wait for reports from our users, or on AARoads, or updated GMSV imagery, before adding it to usanv. A GMSV camera car was on CC 215 approaching the Summerlin Pkwy. from both directions in Feb. 2019, no route number signage.
It could go into our route set for U.S. named freeways, but I'd prefer to wait for route number markers so the parkway can go right into usanv.
