Kentucky Transportation Cabinet
KYTC
Kentucky • United States of America
The Kentucky Transportation Cabinet (KYTC) manages approximately 27,000 miles of state-maintained roads — the third largest state-administered highway system in the US — including major freight corridors I-64, I-65, I-71, I-75, I-24, and the Louie B. Nunn Parkway. Kentucky is home to major distribution hubs for UPS, Amazon, and Toyota, making efficient freight movement a top priority. KYTC administers commercial vehicle permits through the GoKy portal, manages seasonal weight restrictions on secondary roads, and enforces size and weight regulations. The department's traffic management centers monitor interstates critical to the state's logistics economy.
