  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.
Key West is 129 miles (208 km) southwest (229.9 degrees) of Miami, Florida, (about 160 miles (260 km) by car) and 106 miles (171 km) north-northeast (21.2 degrees) of Havana, Cuba. Cuba, at its closest point, is 94 statute miles (151 km) south. Key West is a seaport destination for many passenger cruise ships.
