Martin's Mill Covered Bridge once carried road traffic over Ten Mile Creek west of Marianna, Pennsylvania, at the boundary of Amwell and West Bethlehem townships. In Washington County it was recognized as a historic bridge by the Washington County History and Landmarks Foundation. The bridge itself no longer survives, but its stone wing walls remain at the site. Those surviving elements preserve the location of a former covered crossing and mark the place where the structure once spanned the creek.
