|Subject: Forksville Covered Bridge Thu Jan 13, 2011 7:30 am|| |
The Forksville Covered Bridge is a Burr arch truss covered bridge over Loyalsock Creek in the borough of Forksville, Sullivan County, in the U.S. state of Pennsylvania. It was built in 1850 and is 152 feet 11 inches (46.61 m) in length. The bridge was placed on the National Register of Historic Places in 1980. The Forksville bridge is named for the borough it is in, which is named for its location at the confluence or "forks" of the Little Loyalsock and Loyalsock Creeks.
Pennsylvania had the first covered bridge in the United States, and the most such bridges in both the 19th and 21st centuries. They were a transition between stone and metal bridges, with the roof and sides protecting the wooden structure from weather. The Forksville bridge is a Burr arch truss type, with a load-bearing arch sandwiching multiple vertical king posts, for strength and rigidity. The building of the Forksville bridge was supervised by the 18-year-old Sadler Rogers, who used his hand-carved model of the structure. It served as the site of a stream gauge from 1908 to 1913 and is still an official Pennsylvania state highway bridge. The United States Department of Transportation Federal Highway Administration uses it as the model of a covered bridge "classic gable roof", and it serves as the logo of a Pennsylvania insurance company.Übersetzung Deutsch Französisch4life tri-factor
