The frequency that an Ohio state highway map is updated varies depending on its medium. Paper forms of maps for Ohio are typically updated and released annually to reflect changes made to roads. Conversely, map software and GPS devices receive updates more often and reflect road changes or closures much more quickly.
The Ohio Department of Transportation website provides several options to view the state's highway map. Navigating to the View the Current Ohio Transportation Map page offers PDF documents and JPEG images of the state road map. Additionally, the webpage provides PDF and PNG image files for road maps of major Ohio cities. The ODOT main webpage also handles requests for a complimentary paper hardcopy of the state road map. Those who provide a name and full mailing address can receive a copy.
Private websites like MapsOfTheWorld.com offer an updated map of Ohio for online viewing or purchase. The map features national highways, major roads and larger cities of the state. Additionally, map software websites like MapQuest.com provides an browser-based map of Ohio with frequent real-time updates. The site's map view can be zoomed in to increase the details provided or zoomed out as needed. The site also offers satellite imagery of areas and live traffic updates of state roads.
