In the next village, Dobbs Ferry, US 9 has various views of the Hudson River while passing through the residential section. The highway passes by the Old Croton Aqueduct and nearby the shopping district of the village. After intersecting with Ashford Avenue, US 9 passes Mercy College, then turns left again at the center of town just past South Presbyterian Church, headed for equally comfortable Ardsley-on-Hudson and Irvington. Villa Lewaro, the home of C.J. Walker (1867-1919), the first African-American millionaire, is along the highway here. At the north end of the village of Irvington, a memorial to writer Washington Irving, after whom the village was renamed, marks the turnoff to his home at Sunnyside. Entering into the southern portion of Tarrytown, US 9 passes by historic Lydhurst mansion, a massive mansion built along the Hudson River built in the early 1800s.
