Open this topic on the map Traffic by ZIP code

Traffic in Ohio concentrates on a handful of interstates and the interchanges where they meet: the freeways ringing Columbus, Cincinnati and Cleveland carry far more cars on an average day than any two-lane county road ever will.

This ranks the 25 Ohio ZIP codes whose busiest mapped road segment carries the highest annual average daily traffic count, busiest first, from state and federal traffic counts. The figure describes the single busiest stretch of road inside the ZIP code, not every street in it, so an otherwise quiet ZIP code can still make the list if one interstate happens to cross a corner of it.

How this was measured

ODOT publishes annual average daily traffic, the number of vehicles passing a point on an ordinary day, for its state, US and interstate routes and for about 46,000 miles of county, township and city roads. That is 68,000 miles in all, a little over half of Ohio's 123,000 miles of public road, so most city streets have no count at all. The map shows the busiest counted segment inside each ZIP, from a few hundred vehicles on a township road to about 195,000 on I-270 in Franklin County; the card adds the trucks on it, the total vehicle-miles driven inside the ZIP each day, the busiest counted county, township or city road, and how many segments carry freeway volumes. Counts are the 2025 set from ODOT's Transportation Information Mapping System. The card closes with the fatal crashes NHTSA recorded inside the ZIP from 2020 to 2024: deaths, pedestrians and cyclists, drinking drivers, and the road carrying the most where one road stands out.

1,214 of 1,233 ZIP codes have a figure; ZIP codes without one are left off the list, not counted as zero. Ties are broken by ZIP code.

Every ZIP code's own page carries the full detail behind its figure, and the Traffic topic page ranks the whole state.
