Sewall's Bridge is a singular example of an era when wooden trestle bridges carried highway traffic across New England waterways. It is the earliest pile-trestle bridge for which an authentic construction record exists, and the oldest for which builder's drawings survive. Spanning the York River, it was named for Major Samuel Sewall, Jr., the civil engineer who designed and constructed it.

The first known pumping system providing drinking and wash water in the North American colonies. The building (still standing) is dated 1761, but it was preceded by an experimental frame building dated 1754. Before the Bethlehem built its system, assigned carriers would daily haul water up the hill from a well near the city gate. A wooden waterwheel, driven by the flow of Monocacy Creek, drove wooden pumps which lifted the water through wooden pipes to the top of the hill where the water was distributed by gravity.
