The High Line is a 22-block-long abandoned rail line built in the 1930s, during the height of old industrial New York when the many flourishing companies on Manhattan’s west side used trains to move goods and supplies in and out of the city. Abandoned and partially demolished, the remaining stretch of line is from Gansevoort Street to 30th Street. The elevated structure has now been converted into a mile-and-a-half long urban park.

During Phase I, Silman surveyed the structure and documented – at a general level – the location, sizes, and variations in elevation of the existing structure and issued repair documents for the first phase of the work. The full scope of the structural work included the conditions survey, the design of repairs for all steel and concrete elements, and construction administration.

During Phase II, park landscape and design elements were integrated into the existing structure in Section 1 of the park, which stretches from Gansevoort Street to 20th Street. At the completion of Phase III, the second section of the park, which runs between West 20th and West 30th Streets, will open, doubling the size of the High Line.

The High Line presented many challenging obstacles, such as the extent and scale of the project, as well as the connections, expansion joints, and the roller bearings that make up the railroad viaduct.
