"The High Line was built in the 1930s, elevating rail traffic above the streets, which reduced the accidents in the area. When finally completed, the elevated railway stretched for 13 miles. The final train ran on the High Line in 1980 and sections still stand on the West Side, spanning over 20 blocks. With all the precious land that the High Line is on, there were many that called for the development of the space, but preservationists prevailed, saving the High Line from demolition."
