Detailed Map of Indiana with Cities, Counties and Roads

Navigate Indiana's Diverse Counties and Vibrant Cities on the Interactive Map

Map of Indiana - Indiana map with cities, counties, and roads network. Use this detailed map to explore all 92 counties, their administrative capitals (county seats), major cities and towns, the bordering states of Michigan, Ohio, Kentucky, and Illinois, plus a few clean road references for orientation. We keep highways light because counties are the stars of the map.

Road-light orientation: the Indiana Toll Road skirts the northern counties from the Chicago area to Ohio; I-65 runs Gary-Lafayette-Indianapolis-Columbus-Jeffersonville; I-69 links Fort Wayne-Muncie-Anderson-Indianapolis-Bloomington and continues toward Evansville; I-70 crosses Terre Haute-Indianapolis-Richmond; I-74 angles Illinois-Indianapolis-Ohio; I-64 follows the southern tier near the Ohio River. These are only guideposts so you can follow the grid of counties with ease.
