From Columbia University, the Hudson Greenway goes up to Dyckman Street. The subsequent paths in Inwood Hill Park may get confusing, but there supposedly is a bike path over Henry Hudson Bridge that cyclists can walk their bikes across. However, unable to find the entrance to that path to cross Spuyten Duyvil Creek, I crossed Harlem River Ship Canal via Broadway Bridge instead. This subsequent stretch on Broadway doesn't contain bike paths, but convenient has a wide lane for parked cars, and cyclists can squeeze in with enough space. Continuing northbound, Broadway passes all of the remaining stations of the 1 train and the western edge of Van Cortlandt Park. After W 262nd Street, Broadway enters Yonkers as South Broadway.
The transition is seemingly noticeable. Continuing S. Broadway in Yonkers, the area is highly reminiscent of area in The Bronx. Upon encountering Main Street, downtown Yonkers is approached. The Yonkers Metro North Railroad station is located here, as well as the Waterfront. This area is directly across Hudson River from Alpine, NJ and about 7 miles north of George Washington Bridge. Returning southbound, Riverdale Ave doesn't feature many uphills. The route enters The Bronx and ends at W 230th Street. From that point, Broadway - Dyckman - Hudson Greenway takes back to Morningside Heights for an overall of nearly 24 mile trip, devoid of major difficult uphills.
