Pennsylvania → Michigan · Interstate 376 / Interstate 79
Wrapping up the trip, the homebound leg from Pittsburgh, Pennsylvania, back to Detroit, Michigan, layers another 389 km (242 miles) onto the odometer along Interstate 376 / Interstate 79 and tacks on roughly 3h 42m to the cumulative day. Drivers leaving Pittsburgh, the historic Steel City at the confluence of the Allegheny and Monongahela rivers, usually pull into Detroit, the Motor City and historic capital of the American auto industry, with an empty calendar but an inbox of paperwork — toll receipts, fuel invoices, visit reports, and meeting minutes all need to be tagged inside the cab before they get tangled with other paper stacks at the office. Average fuel spend on the return holds near $32.57 for the 35.4 liters (9.4 gallons) burned. Mileage reimbursement for the homeward stretch totals $167.27 at the $0.43/km benchmark.
