Alabama → Indiana · Interstate 65 / Interstate 20
Tackling the 823 km (511 miles) that separate Birmingham, Alabama, from Indianapolis, Indiana, in a single push demands long-haul planning: 7h 50m behind the wheel along Interstate 65 / Interstate 20 exceeds the safe ceiling on continuous driving. Schedule a midpoint overnight, driver swap (where applicable) and a mandatory pre-trip inspection. Pulling out of Birmingham (the largest city in Alabama and former steel-industry capital of the Deep South) toward Indianapolis (the capital of Indiana and home of the Indianapolis 500 motor race), total fuel use reaches 74.8 liters (19.8 gallons) of regular unleaded (about $68.82), on top of consecutive tolls and a probable hotel night. Gross outbound reimbursement, against the IRS standard mileage rate (2025) schedule of $0.43/km, lands at $353.89. Capture lodging and meals in separate fields of the Clara receipt so they don't get tangled with the pure mileage calculation. The typical corporate policy authorizes a hotel per-diem up to a certain ceiling and meals with a limit per occurrence, amounts that must be substantiated with a fiscal invoice in the contributor's or the company's name. Confirm before the trip the prevailing ceiling per the internal HR table, and verify that the chosen hotel issues an invoice in the format the corporate fiscal system accepts, avoiding later disallowance of the amount.
