Road Trip Guide: Bethlehem, PA to Nashville, IN

Beginning in Bethlehem, Pennsylvania, founded in 1741 by Moravian settlers, this road trip traverses a corridor that has evolved from Native American paths to a multi-state highway network. The route uses I-78 West to I-81 South, then I-64 West and I-65 North into Indiana, covering just over 500 miles. A notable local driving quirk: near the Pennsylvania-New Jersey border, I-78 has a sharp curve known as the 'Lehigh Gap' where visibility drops during fog.
