The Hutchinson River Parkway in Pelham Bay Park replaced the old Split Rock Road in the park. The original roadway was an undivided, limited-access parkway, designed with gently sloping curves, stone arch bridges, and wooden lightposts. The original section included bridle paths along the right-of-way. There was also a riding academy where the public could rent horses. The parkway is named for Anne Hutchinson and her family, and passes through the part of the park near where the Hutchinsons were killed by the Siwanoy. The modern-day parkway was extended south from Westchester through Pelham Bay Park in December 1937.
