Manhattan high line:
In 1930s elevated rail line was built in Manhattan. In order to provide goods for manufactures , there were stations inside the manufactured buildings. The railway was elevated to be safe for pedestrians and cars. But after a while manufacture disappeared from Manhattan and the rail station remained unused. In 2000s the city decided to chang it to elevated park. Today most part of the park have been constructed. The elements of the park are included different planting, pavement and benches. Designers kept some  of the rail way. The shape of some part of elevated rail line have been changed. As people walk in the park they experience different spaces. In some parts of park high rise building are closer but in other part the gap between building and park is further. Sometimes park crosses inside a high rise building. High line park have a good view to river,streets and high rise buildings, however in other parts it has view to parking lots and roof of other buildings. Totally it can be seen that this structure is successful now. large amount of people come to this park every day and it makes them to walk long distant in the city.
