Another extant remnant of the estate is the partially paved-over red-brick pathways near Corbin Circle. It was originally a serpentine driveway with multiple switchbacks that continued down to Riverside Drive, now the northbound lanes of the Henry Hudson Parkway. The brick was intended to help horses ascend the driveway's 6% slope. By 1936, when the park was built, the driveway had been converted into a pedestrian path. Though the gates to the driveway were removed, the granite posts were left standing. An overgrown section of the driveway used to connect with the northbound Henry Hudson Parkway, but in 1994, the New York State Department of Transportation added a Jersey barrier to block off access to the driveway.
