The 1854 Sachs Covered Bridge, also known as Sauck's Covered Bridge and Waterworks Covered Bridge, is a 100-foot, Town truss covered bridge over Marsh Creek between Cumberland and Freedom Townships, Adams County in Pennsylvania. The bridge was also known as the Sauches Covered Bridge at the time of the Battle of Gettysburg.

During the American Civil War, both the Union and Confederate Armies used the bridge in the Battle of Gettysburg and its aftermath. It is reportedly known to be severely haunted as a result.

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. After a plan in 1960 to replace the bridge, the Cumberland Township officials voted to close the bridge to vehicular traffic, while leaving it open to pedestrians, on May 9, 1968.

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 "crisscrossed" to form a lattice. The bridge was one of the few remaining Town truss bridges in Pennsylvania. The bridge is 100 feet long and 15 feet 4 inches wide.

Total length: 101.2 ft.
Deck width: 15.8 ft.

Of the 1,500 covered bridges that once stood in the state of Pennsylvania, as of 2019, approximately 200 remain.
