  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 Miami, drivers can take the Florida Turnpike and then follow Highway 1 south until it ends at Key West. The drive takes just over three hours when there is little traffic, although drivers should note that Key West has strict speed limits, especially through reserve areas. Step 3. Catch a bus or shuttle.
