The transport infrastructure of the Cayman Islands includes a 785 kilometre long public road network with seven active bus routes. There are three airports on the islands.
Roads
The National Roads Authority, which oversees the development and maintenance of roads in the Cayman Islands, was established on 1 July 2004. Traffic surveys were conducted in 1999 and 2016.
Of the people whose main mode of transportation to work was in a private vehicle in 2021, 52% lived in George Town, 21% in Bodden Town, 20% in West Bay, and 2% each in North Side and East End. East End was the only settlement in which private vehicles were not the main method of transportation to school for the majority of the population.
In 2021, 84% of people whose main mode of transportation to work was bicycles lived in George Town. Legislation on electric bicycles and scooters requiring a driver’s license and other regulations was passed in 2018, but did not come into effect until 2026.
As of 2024, there are 785 kilometres of paved roads. In March 2024, there were over 50,000 registered vehicles and over 62,000 licensed drivers in the Cayman Islands.
