Boston to Washington is about 480 miles (773 km) by road and 394 miles in a straight line. The drive takes around 8 hr 8 min and a nonstop flight is about 1 hr 13 min. The distance is the same in reverse, from Washington to Boston.
Boston to Washington, D.C. runs the length of the Northeast Corridor — the busiest, most densely populated travel corridor in the United States. Connecting two of America's most historic cities and passing through New York, Philadelphia, and Baltimore, it's a route with more transport options than almost any other in the country.
Unusually for the US, the train is a genuinely excellent option here: Amtrak's Acela and Northeast Regional services link the city centres directly, often beating both driving and flying door-to-door once you account for traffic and airport time.
Stops Along the Way
About 4 hours from Boston — the major waypoint, and a tempting stopover.
Historic Philadelphia, with its revolutionary landmarks, sits roughly two-thirds of the way.
The Inner Harbor city, close to D.C. and a worthwhile final stop before the capital.
The route threads through the megalopolis — efficient but prone to heavy traffic.
Meeting someone from Washington? Find the exact halfway point between Boston and Washington so neither of you drives the whole way — or plan evenly-spaced rest and fuel stops along the route.
Tips for This Trip
Consider the train
Amtrak connects Boston and D.C. city-centre to city-centre, often more relaxing and competitive than driving or flying once traffic and airport time are factored in.
Driving means heavy traffic
The I-95 corridor through New York and the cities is among the most congested in the US. Budget extra time and avoid rush hours.
Flying isn't always faster
Short flight times are offset by airport procedures at both ends. For this corridor, the train is frequently the smarter choice.
