Connecticut → Pennsylvania · Interstate 84 / Interstate 91
What does it actually cost to drive from Hartford, Connecticut, to Pittsburgh, Pennsylvania? The hard numbers: 744 km (462 miles) of pavement primarily along Interstate 84 / Interstate 91, 7h 5m behind the wheel, and roughly $62.19 in fuel alone — that is 67.6 liters (17.9 gallons) of regular unleaded at a 0.92 USD/liter benchmark. Anyone leaving Hartford, the capital of Connecticut and the long-standing insurance capital of the United States, typically carries samples, signed proposals, or service equipment to deliver in Pittsburgh, the historic Steel City at the confluence of the Allegheny and Monongahela rivers, and aims to be home the same evening. It is worth confirming whether the haul fits inside your daily hours-of-service window or whether an overnight at a midpoint hotel makes more sense. Applying the IRS standard mileage rate (2025) mileage rate of $0.43/km ($0.69/mile), the gross outbound reimbursement settles at $319.92.
