The popular elevated park known as the High Line will double in length this Wednesday following the opening of the second section, running from 20th Street to 30th Street in Chelsea.
Officials will cut a ribbon the day before the official opening.
Mayor Michael Bloomberg, Council Speaker Christine Quinn, Friends of the High Line Co-Founders Joshua David and Robert Hammond and other officials will attend the event.
Built in the 1930s to carry freight, the High Line spans a total of 1.5 miles, running from Gansevoort Street in the Meatpacking District all the way up to 34th Street along Manhattan's West Side.
The trestle runs through blocks and buildings, under The Standard Hotel, and offers a unique insider view of New York City -- serving as a reminder of its manufacturing roots.
The Giuliani administration set the railway for demolition, but Bloomberg saved the space from this outcome and converted it into a park.
Since its opening two years ago, the park has become home to dance performances, photo shoots, and a trendy crowd of tourists and New Yorkers alike. The New York Times reported that two million people visited the park last year.
The third section, running up to 34th Street, remains closed to the public. Its opening date has not been set.
The park is open daily from 7 a.m. until 11 p.m.
