I added two more points for new interchanges/GSVs: 428 in Chase, WhiLakeRd in Carlin. Hope one of those matches the one you found.
No, didn't know about 428. Didn't have any proof on that one for exit number or being open yet. Hence why I didn't mention it to play it safe, as people have been know to jump the gun on OSM and put the wrong exit number.
What I had caught, was the number for '478', as when I made the original post, there was no GSV there due to the slight realignment.

Anyways, I 'did' just find another exit that should be added. LOL! (Sorry.)
