Bethlehem PA to Tarrytown NY Road Trip Guide

This 110-mile route follows the historic corridor between Bethlehem, PA and Tarrytown, NY, largely via I-78, I-287, and the Garden State Parkway. The drive typically takes 2 hours without traffic, but the real journey lies in the stops along the way. Notably, the route crosses the Delaware Water Gap, a geological marvel carved by the Delaware River, marking the border between Pennsylvania and New Jersey.

I-78 has wide, paved shoulders and emergency call boxes every 2 miles. Speed limits range 65 mph (PA) to 55 mph (NJ). Winter driving requires caution; black ice forms on bridges near the Delaware River.

Best stops for families: The Crayola Experience (Easton, PA, 15 min from Bethlehem) offers hands-on color labs. The Turtle Back Zoo (West Orange, NJ) is a kid-friendly stop with a carousel. For a quick break, the Montclair Art Museum combines culture with a garden.
