This summer an 800-metre segment of the High Line opened to the public. The elevated railway once bore freight traffic on Manhattan’s southwest edge, but had been derelict since 1980. Varying in width from 10 to 20 m, the platform gently navigates the ubiquitous grid, while its rhythm is determined by a combination of existing spatial situations and new elements. A hotel by Polshek and Partners, for example, straddles the park at one such juncture. And elsewhere the platform is divided into multiple levels or penetrates a building.
