This is the Sach's bridge at Gettysburg. It was built in 1854 and during the battle was called the Sauches bridge. Union troops crossed this bridge on the way to reinforce General John Buford fighting on McPherson's Ridge July 1, 1863. Most of the Confederate Army retreated across the bridge after the battle. The bridge was made into a pedestrian bridge in 1968. It is supposedly haunted and has been featured on programs about the paranormal.
