The Sachs Covered Bridge was built around 1854 at a cost of $1,544. On July 1, 1863, the bridge was crossed by the two brigades of the I Corps of the Union Army heading towards Gettysburg. The III Corps also crossed the bridge heading to the Black Horse Tavern. Four days later, the majority of General Robert E. Lee's Army of Northern Virginia retreated over the bridge after the Union victory in the Battle of Gettysburg.
The bridge was designated Pennsylvania's "most historic bridge" in 1938 by the predecessor of the Pennsylvania Department of Transportation, the Department of Highways. The Cumberland Township officials voted to close the bridge to vehicular traffic, while leaving it open to pedestrians, on May 9, 1968. It was listed on the National Register of Historic Places on August 25, 1980.
On June 19, 1996, a flash flood knocked the bridge from one of its abutments and it incurred substantial damage; an iron bridge on the Marsh Creek was also heavily damaged and another destroyed. A $500,000 restoration on the bridge was already in progress before the flood; an additional $100,000 was raised to repair the damage incurred. The bridge was rededicated on July 21, 1997.
The Sachs Covered Bridge is a Town truss covered bridge. The truss design was developed by Ithiel Town of Connecticut and consists of wooden beams "cris-crossed" to form a lattice.[3] The bridge was one of few remaining Town truss bridges in Pennsylvania.[2] The bridge is 100 feet (30 m) long and 15 feet 4 inches (4.67 m) wide.
