Right.  There are extreme exceptions (links below to imagery on
approach), but there's no standardized sign specifically for the
situation.  You still know it, though:

http://g.co/maps/dv9ab (approaching sharp, blind and frequently
congested freeway curve)
http://g.co/maps/agjnm (sharp freeway curve approached in the previous
link, no horizontal visibility thanks to tunnel, no lane change zone
continues to end of freeway)
