Transportation in Guam

The United States territory of Guam has no railways or freeways, nor does it have a merchant marine. Apra Harbor is the largest port, serving almost all commercial traffic, including cruise, cargo and fishing vessels. There are smaller harbors located on the island which serve recreational boaters. Roads are primarily paved by a mixture of coral and oil, and when the mixture gets wet it tends to have oil float to the surface, making the roads dangerous. This is one of the reasons the speed limit on most of the island is 35 mph. But, during road repair or maintenance, a different mixture of asphalt that is not as slippery is used. Its main commercial airport is the Antonio B. Won Pat International Airport.
The Guam Department of [Public Works] is the government agency in charge of building, managing, and maintaining transportation infrastructure and equipment.
