if there is lots of traffic on the Venetian Cswy you might want to consider to get back East and get the Airport expressway from South Beach otherwise you can get the Airport Expreswaw going West on the Venetian Cswy and then go South on Biscayne till you get to the Airport Expressway.
In both cases could take you from 20 to 45 minutes assuming a normal traffic situation.
If you want to go to my website you can easily see the map.
