The task included the complete conservation and restoration of marble, stone, and brick masonry, accompanied by a comprehensive structural analysis of the entire Arch. Of major importance is the restoration of the interior Guastavino stair that provides access to spaces within the Arch and the roof. An exterior illumination campaign and site improvements were also implemented including drainage, paving, and fencing. It was completed in 2004 for the New York City Department of Parks and Recreation.
