Guam has no railways, nor does it have a merchant marine. The only port is Apra Harbor. Due to the construction of roads largely from coral (which is exceedingly slippery when wet), the top speed limit island-wide is 35mph. Its main commercial airport is the Antonio B. Won Pat International Airport.
