It records only administrative status, including a National Historic Landmark marking and a withdrawal of designation dated 08/25/2014.","narrative":"This record concerns the Full Scale Tunnel, a structure in the independent city of Hampton, Virginia, listed on the National Register of Historic Places on 3 October 1985 under reference number 85002796. The only material available is an administrative locator card, not the full nomination, so it contains no physical description, construction history, architect, or argument for significance. The card marks the property as a National Historic Landmark and also records a withdrawal of designation with a date of 08/25/2014, followed by an update noted as 7/29/15. The card does not explain the reason for the withdrawal, and it says nothing about whether the structure is standing, in use, or vacant. Because the narrative sections of the nomination are absent, nothing further about the tunnel's purpose, age, or features can be stated from this document alone.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"The locator card records a withdrawal of designation dated 08/25/2014 and an update dated 7/29/15.
