Hawaii Honors 70 Years of Interstates | Honolulu News

Hawaii’s celebrating 70 years of the Eisenhower Interstate System with custom signs on the H-1, H-2, and H-3 freeways—costing $8,000 for six signs, up until 2027. Designed by the Federal Highway Administration, this is part of a national tribute to the 1956 highway act that revolutionized travel, defense, and commerce. Oahu’s freeways have a storied past: the H-1 began before the federal program, while the H-3 battled fierce opposition before completion. A proposed H-4 freeway never came to be. Meanwhile, federal planners eye nationwide expansion, and Hawaii’s H-1 continues to evolve with widening projects and interchange upgrades.
