The concurrency between US 1 and US 9 that began in New Jersey ends at the first exit from I-95 on the George Washington Bridge, when US 9 heads north via 178th and 179th streets to Broadway. Broadway passes through the Washington Heights neighborhood and then into Inwood, the northernmost neighborhood on the island. The region in which US 9 passes through has a large Latino immigrant population. The northernmost section of the New York City Subway's underground IND Eighth Avenue Line ( train) runs along Broadway between Dyckman Street and the Inwood–207th Street terminal. On the corner of 204th Street is the Dyckman House, the only original farmhouse left in Manhattan and a National Historic Landmark.
