It was listed in October 1985. The only material available is an administrative locator card from the National Park Service, and it has no physical description, construction date, designer or statement of significance. The card shows that the resource was marked for removal or withdrawal of designation, with a date of 08/25/2014, and it lists a separate update dated 7/29/15. The card gives no cause for the removal. Other fields on the card, such as national landmark status and the multiple-resource or thematic group name, are blank or unreadable in the text. Because of this, nothing can be said here about what the tunnel was used for, who built it, or what qualities led to its original listing. A reader who wants those details would need the full nomination narrative, which is not part of this record.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":"The locator card records a removal or withdrawal of designation dated 08/25/2014.
