Transportation & Infrastructure Guide in Guam

Public transit, airports, and getting around

Guam, a strategic U.S. territory in the Pacific, relies heavily on roads and air travel for its 168,783 residents due to limited public transit. Challenges include sparse bus services with long waits and inadequate signage, but strengths lie in federal infrastructure funding exceeding $200M for roads, transit, airports, ports, and broadband. The 2030 Guam Transportation Plan guides multimodal improvements amid military buildup, offering car rentals, taxis, and rideshares as primary options for visitors exploring the 212 sq mi island.
