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.
How to Get There. By car: Key Largo is slightly more than an hour from Miami; Islamorada is another twenty-five minutes south on U.S. 1 (the Overseas Highway). Take the Florida Turnpike South to Florida City where it ends. U.S. 1 continues from that point south through the Keys. To reach Everglades National Park, head west from U.S. 1 onto State Road 9336/SW 344th Street in Florida City and follow the signs to the park entrance.
