Kentucky → Missouri · Interstate 65 / Interstate 64
Outside sales reps regularly slot the Louisville, Kentucky, → St. Louis, Missouri, leg into the weekly visit calendar precisely because the 459 km (285 miles) along Interstate 65 / Interstate 64 fit inside 4h 22m of continuous driving and still leave room for a full client meeting before the homeward trip. Pulling out of Louisville — the largest city in Kentucky and home of the Kentucky Derby horse race — the route crosses light industrial zones, then farmland, before opening into St. Louis, the historic Gateway to the West and a major Mississippi River freight port. The budget line item calls for 41.7 liters (11.0 gallons) of regular unleaded (about $38.36 at the national average benchmark of 0.92 USD/liter), plus discretionary tolls billed per axle. Reimbursement math, against the IRS standard mileage rate (2025) schedule of $0.43/km, returns $197.37 to the contributor at week-end.
