Ohio National Highway System (NHS)...
The National Highway System (NHS) is part of the Federal Aid Highway System. The term “Federal-Aid Highway” means a public highway eligible for assistance under Title 23, United State Code (USC) other than a highway functionally classified as a local road or rural minor collector.
The NHS consists of the Eisenhower Interstate System and other roadways important to the nation’s economy, defense, and mobility, as defined in Title 23, USC § 103. In general, the NHS National Highway System (NHS) consists of highway routes and connections to transportation facilities that shall:
(1) serve major population centers, international border crossings, ports, airports, public transportation facilities, other intermodal transportation facilities and other major travel destinations;
(B) meet national defense requirements; and
(C) serve interstate and interregional travel and commerce.
The NHS for Ohio was developed by ODOT in cooperation with Ohio’s Metropolitan Planning Organizations (MPOs) Rural Transportation Planning Organizations (RTPOs), county engineers and other local officials. The current NHS System for Ohio was approved by the Federal Highway Administration (FHWA) on August 11, 2017.
