The Ashuelot Covered Bridge is located at the center of Ashuelot, NH. It is a Town lattice truss bridge, spanning the Ashuelot River in a roughly north-south orientation. It consists of two spans with a total length of 178 feet (54 m). The total width of the bridge is 29 feet (8.8 m), and has a central roadway and sidewalks (measuring 3'10" in width) on each side. The bridge rests on stone abutments and a central pier. The abutments have been reinforced with concrete since the bridge was built, and the central pier has been protected by a metal breakwater.

The William H. Chandler Chemistry Laboratory was conceived and planned by William Henry Chandler (1841-1906), professor, chairman, librarian, and acting president of Lehigh University. Designed by Philadelphia architect Addison Hutton and erected between 1884 and 1885 at a cost of $200,000, the building set the standard for laboratory construction for the next half century.
