Hillsgrove Covered Bridge

The Hillsgrove Covered Bridge is a Burr arch truss covered bridge over Loyalsock Creek in Hillsgrove Township, Sullivan County, in the U.S. state of Pennsylvania. It was built c. 1850 and is 186 feet long. In 1973, it became the first covered bridge in the county to be placed on the National Register of Historic Places. The bridge is named for the township and nearby unincorporated village of Hillsgrove, and is also known as Rinkers Covered Bridge for an adjoining farm.

Pennsylvania had the first covered bridge in the United States, and has had the most such bridges since the 19th century. They were a transition between stone and metal bridges, with the roof and sides protecting the wooden structure from the weather. The Hillsgrove bridge has load-bearing Burr arches sandwiching multiple vertical king posts on each side, for strength and rigidity. It was built by Sadler Rodgers, who also constructed the nearby Forksville Covered Bridge in the same year, with a similar design.
