Written By: Bitumen, dense, highly viscous, petroleum-based hydrocarbon that is found in deposits such as oil sands and pitch lakes (natural bitumen) or is obtained as a residue of the distillation of crude oil (refined bitumen).
  About 3.5 hours-maybe 4 depending on road construction. The hardest part is getting out of Miami to Key Largo-then it's a 2 lane highway through all the keys to Key â¦ West with alot of traffic lights in between. If you are coming from Miami-definitely take the toll road.
If you are more south, so any place from Midtown all the way to South Beach/Coral Gables should take you about an hour, including traffic. If you are living around North Miami, it should take you about 30 minutes. Lastly, if you are more north, Aventura area, it should only take you about 15 to 20 minutes.
