South Beach travel question?

Travel Info
I'm curious if anyone can tell me about how far (miles) the Port of Miami is from Downtown Miami?

Travel Tips

Port of Miami is actually in Downtown Miami ~ East of US1 (Biscayne Boulevard at N.E. 6th Street)

Others
Around 10 miles
10 Miles NO WAY ! Maybe Maybe--3 miles
The port of Miami is right next to downtown miami, duh. Take it from someone who lives in Miami, its right next to it. Just cross the big bridge and your in Downtown Miami. Welcome!
10 miles and 1 direct bus route
It depends on where "downtown" you want to go, but just a short drive. I've lived here my whole life.
If you jump from the ship when you get to the dock, you can swim to south beach. Ha ha ha ha..... just a joke but to let you know how close to South Beach the Port of Miami is.
