Hershey to Plymouth: Ultimate Road Trip Guide

The 390-mile journey from Hershey, Pennsylvania to Plymouth, Massachusetts weaves through six states, crossing the Delaware River and traversing the Connecticut coastline. This drive, primarily via I-78, I-95, and I-495, typically takes 6 to 7 hours without stops — but the real value lies in the detours. The route parallels historic corridors used by early American settlers and passes within a stone's throw of Manhattan, offering a blend of industrial heritage, modern commerce, and coastal charm.

Hershey itself is the birthplace of the chocolate bar, while Plymouth anchors the nation's founding story with Plymouth Rock. This guide unpacks everything from fuel economics to pet-friendly stops, ensuring you experience the road's full texture.

The backbone of this trip is Interstate 78 East from Hershey to the New Jersey Turnpike, then I-95 North through New York and Connecticut. Traffic around New York City is unpredictable; rush hours can add 2 hours. Tolls on the New Jersey Turnpike and I-95 in Connecticut and Massachusetts average $25–$35 for a standard car. Alternative routes like the Garden State Parkway or US-202 can offer scenic diversity but add time.

Fuel stations are abundant along the corridor, but prices vary. In Pennsylvania, diesel and gasoline are generally cheaper than in New York or Massachusetts. Expect to refuel twice: once near the Pennsylvania/New Jersey border and again near New Haven, Connecticut.
