The Hawaii Department of Transportation (HDOT) maintains the smallest state-maintained system of state highways in the country. It consists of Interstates, state highways, and secondary state highways, totaling approximately 1,013 miles (1,630 km).[1]
The state's four Interstates, all located on O‘ahu, are built to mainland standards unlike their counterparts in Alaska and Puerto Rico. The first three routes (H-1, H-2, and H-3) were approved in 1960, while an auxiliary route (H-201) was added in 1989.[2]
