Английская Википедия:Bluff Dale Suspension Bridge
The Bluff Dale Bridge is a historic cable-stayed bridge (not a suspension bridge) located near Bluff Dale, Texas, United States. Built in 1891, the bridge spans Шаблон:Convert across the Paluxy River. The road deck is Шаблон:Convert above the river and held in place by fourteen Шаблон:Convert cables attached to the towers made of Шаблон:Convert iron pipe.[1]
History
The bridge was originally constructed across the river on a dirt road that became Texas State Highway 10, which is now U.S. Route 377. In 1933, a new bridge was built to handle the increasing traffic on U.S. 377. The old bridge was relocated Шаблон:Convert upstream in 1934 and extended from Шаблон:Convert.[2]
The bridge was added to the National Register of Historic Places on December 20, 1977. The bridge is on Preservation Texas' 2009 list of most endangered places due to its poor condition and lack of funds for restoration. It was closed to vehicular traffic in 1989 because of its advanced state of deterioration.[3]
Structure type
Despite the name given in Historic American Engineering Record documentation, the Bluff Dale Suspension Bridge is actually a cable-stayed structure.[4] Its deck is suspended from multiple layers of stay cables radiating from the towers, some terminating at the deck and others running continuously from one tower to the other. This pattern of cables was established in designer Edwin Elijah Runyon's first U.S. patent, Шаблон:Patent.[5] It is known as one of only two examples of Runyon's patents, along with the Barton Creek Bridge in Huckabay, Texas. Its hand-twisted wire cable and non-traditional use of wrought-iron pipe components make it a notable example of vernacular American bridge construction.
