This route avoids most tolls except the optional express lanes on I-66 inside the Beltway. Gas stations and rest areas are plentiful along the interstates, with clusters every 30-40 miles.

Traffic Patterns

Expect heavy congestion leaving DC between 3-7 PM on weekdays. Saturdays are relatively smooth. The Appalachian mountain section (Cumberland to Morgantown) has winding stretches; drive with caution in rain or fog.

Road quality is generally excellent, with well-lit interstates and clear signage. Be alert for deer crossings in rural Maryland and West Virginia, especially at dawn/dusk. Winter driving can bring snow and ice in the mountains; check forecasts before departure.
