Driving help: Cosmo to Rio

Besides the standard Las Vegas Blvd down to Flamingo and hang a left - are there any back/utility roads I can take out of Cosmo to get to Rio without sitting in the traffic of Las Vegas Blvd? I know the Cosmo garage will let you out on either side - don't know if it's any quicker to take the further exit then a right and another right somewhere? Or if I can come out of the Bellagio side of the Cosmo garage, then turn left instead of right towards the strip?

Any ideas?

 

To clarify, I scribbled on a map and attached... I'm trying to avoid the red route from Cosmo to Rio... and take one of the purple routes. If I-15 is a good option I am open to that too. Just not sure what roads, if any, can help me here. Also might be a little more winding of a route than I'm making it- and that's fine too. Thanks for your help.

 

Frank Sinatra Drive?

 

Take Harmon west over the 15 to Dean Martin Dr. Go north and drive right into the Rio.

Note: when you make that right from Harmon, that's Aldebaran Ave and then slight right to Jerry Lewis Way which empties you into Dean Martin.​

 

Awesome, thank you!
