Harpers Ferry to Gary Drive: Epic Road Trip Guide

This 600-mile journey from Harpers Ferry, WV to Gary, IN traces the historic migration path from the Potomac to the Great Lakes. The route follows US-340 to I-70, then I-76 (Pennsylvania Turnpike) and I-80/I-90 (Ohio Turnpike) before merging onto I-65 for the final stretch. One little-known fact: this corridor roughly parallels the old National Road (US-40), America's first federally funded highway, which began in Cumberland, MD—just 45 minutes south of Harpers Ferry.

The estimated drive time is 9.5 hours without stops, but savvy travelers know the real reward lies in the detours. Spanning five states (West Virginia, Maryland, Pennsylvania, Ohio, Indiana), the trip crosses the Eastern Continental Divide at the Allegheny Front, dropping from 2,000 feet to 600 feet elevation.
