Massachusetts → District of Columbia · Interstate 90 (Massachusetts Turnpike)
Before turning the key for Washington, District of Columbia, out of Boston, Massachusetts, run through the pre-trip checklist: registration card in the glovebox, current insurance card on your phone, working SunPass or E-ZPass transponder for the electronic toll plazas along Interstate 90 (Massachusetts Turnpike), and a printed backup of the destination address in case GPS reception drops. The locked itinerary measures 748 km (465 miles) with an optimistic estimate of 7h 7m if cruise control sits steadily within the posted limit. Pulling out of Boston, the New England capital and one of the oldest US cities, the road eventually delivers you to Washington, the capital of the United States and seat of the federal government. Schedule departure outside the morning rush window and pack a thermos of coffee to skip an unscheduled stop in the first hundred miles. Budget around $62.56 just for the pump (68 liters / 18.0 gallons of regular unleaded) plus headroom for tolls. Outbound reimbursement at $0.43/km equals $321.64 cleared to the driver.
