 In Manhattan, this has led to nearly all trucks being forced onto local streets as the island has only one short Interstate (the Trans-Manhattan Expressway) passing through Washington Heights, a neighborhood in Upper Manhattan.Some regions of New York have parkways that are not owned or maintained by a state agency.Westchester County, for example, contains some highways that were originally part of the TSPC and WCPC, while Suffolk County has preserved a section of the former Long Island Motor Parkway (LIMP) for current driving and built their own roads on land originally reserved for the LISPC.
