  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.
From Fort Lauderdale airport to Key Largo is approx. 85-90 miles. Miami International airport to Key Largo is approx. 55-60 miles. How long it takes to drive each distance would depend upon the traffic and time of day. Rush hour on the turnpike or Palmetto or Dolphin can be like a parking lot. Miami is south of Ft. Lauderdale, so it is definitely closer to Key Largo. Key Largo is the closest of the Keys- about an hour from Miami airport.
