As of December 31, 2024, there were 138,993 miles of roads, streets and highways in Kansas. Average daily travel was 86,600,466 vehicle-miles. This marks an increase of 18 miles (0.01%) in total mileage and a decrease of approximately 664,000 vehicle-miles (–0.76%) traveled compared to 2023. Mileage increase since 2023 includes some highway re-alignments but is mostly due to rounding differences from a change in data precision. County and city road mileage has not been updated.
The Kansas State Highway System (SHS) including City Connecting Links (CCL) totals 10,295 miles and carries an average daily travel of 45.3 million vehicle-miles, which is 3.0% lower than 2023. The Kansas Turnpike (KTA) is 239 miles long, with 5,459,097 daily vehicle-miles of travel, reflecting a 2.6% decline from 2023. Interstate, US and Kansas routes make up 7.58% of the total Kansas road mileage and carry 58.6% of total travel.
Under 23 CFR 460 the State must report annually to the federal government about the extent of the roadway network in a Mileage Certification to FHWA. This data is used for apportionment of highway safety funds. Details of road inventory and usage are reported separately in the Highway Performance Monitoring System.
Under Kansas Statutes Annotated Section 79-3425C, portions of the fuel tax money collected by the State are distributed to County and City governments based on net mileage and road usage. The KDOT certifies these values annually in a Transmittal to the State Treasurer Per the KSA, the networks reported for Travel by County exclude the Interstate system, and Mileage by County includes all roads.
