Haw. Rev. Stat. § 264-36: Conformance with county general or master plans.

All federal-aid highways shall conform to the general or master plans of the respective political subdivisions of the State unless the conformance jeopardizes the receipt of federal aid, in which case the governor, by executive order, may set aside the general or master plan to the extent any conflict prevents the receipt of federal aid on any given project or the prosecution of the work thereunder.
