Pennsylvania → Pennsylvania · Interstate 376 / Interstate 79
Before turning the key for Philadelphia, Pennsylvania, on the homeward run from Pittsburgh, Pennsylvania, do a quick inventory sweep of onboard equipment: proposal binder, undelivered promotional items, and visitor badge should each go into a separate compartment so nothing slides into the footwell during a sharp brake. Interstate 376 / Interstate 79 accepts the 488 km (303 miles) of the return in roughly 4h 39m. Pulling out of Pittsburgh (the historic Steel City at the confluence of the Allegheny and Monongahela rivers), the road eventually puts the driver back in front of the urban skyline of Philadelphia (the birthplace of American independence and sixth-largest US city). Refueling sits near $40.85 for the same 44.4 liters (11.7 gallons) at the EIA national average benchmark. Return reimbursement, calculated against $0.43/km, returns $209.84 into the driver's wallet. Snap the closing odometer with the phone camera and attach it directly to the Clara receipt — internal controls accept photographic evidence without a supplementary spreadsheet.
