Adams Covered Bridge is a historic covered bridge in Morgan County, Ohio, spanning San Toy Creek near Malta. Also known as the San Toy Bridge or the Adams–San Toy Covered Bridge, it was built in 1875 as a 58-foot span using a multiple kingpost truss, a simple timber design common on small rural bridges of its time. The bridge no longer carries traffic and is valued chiefly for its historical importance. Its preservation was recognized in 1999 when it was added to the National Register of Historic Places.
