From here to the state line, US 202 parallels, and has largely been supplanted by, I-287, which during its construction dumped traffic onto US 202. US 202 continues through Morristown to Morris Plains with an intersection with Route 53. With a few exceptions, US 202 is maintained by counties rather than the New Jersey Department of Transportation north of Route 53. The only sections of US 202 in New Jersey north of Route 53 that are state-maintained are at the I-80 interchange, at the US 46 intersection, along the Route 23 concurrency, and at the I-287 interchange in Oakland.
