US 202 extends from Wilmington, Delaware, to Bangor, Maine. It primarily passes through rural areas, avoiding major cities such as New York, Hartford, and Boston. In New Jersey, it is marked as a north/south route, although it is considered an east/west route in other states such as New York. It enters New Jersey from Pennsylvania on a bridge over the Delaware River. There is a short expressway section for a couple of miles near the state line. The expressway then ends and becomes a four-lane divided highway with traffic lights. It runs northeast to Somerville, where it merges with US 206. The US 202/US 206 runs north from Somerville to Bedminster, crossing I-287 twice. It then splits off and becomes a two-lane undivided road. It runs northeast, parallel to I-287, to Morristown and then to Parsippany, where it crosses I-80. North of Parsippany, it turns to the east until Wayne, where it is multiplexed with NJ 23 north. After a couple of miles, it splits off and runs northeast to the New York-New Jersey state line.
