The Pine Grove Covered Bridge spans the East Branch of Octoraro Creek on the border between Lancaster County and Chester County in Pennsylvania. It is the longest covered bridge in Lancaster County. The bridge was built in 1884 by Elias McMellen.
The bridge has a two-span, wooden, double Burr arch truss design with the addition of steel hanger rods. The bridge's deck is made from oak planks. It is painted red, the traditional color of Lancaster County covered bridges on the outside.
It was listed on the National Register of Historic Places in 1980.
The dam seen under and beyond the right side of the bridge is part of the Chester Water Authority. When I visited in 2019 there was graffiti on the left end of the bridge (Photoshopped out of the above picture).
