Double-arch Sandstone Bridge
Double-arch Sandstone Bridge or more commonly known as the Sands Bridge, is a historic dry stone arch bridge over the Spicket River on Hampshire Road in Methuen, Massachusetts. Built without mortar between the stones, parts of it date back to 1735. It was used to handle traffic between Methuen and Salem, New Hampshire.

The location, along the old Dracut Path, was a marshy area of the Spicket River that could be forded by horse or cart. The ford eventually was bridged. The earliest town record, from the Town meeting of 1730, show a simple plank bridge was used which required regular maintenance at the cost of the township. The wooden bridge was replaced with the more durable stone arch bridge in 1835. Solid abutment supports were constructed on each river bank. A wooden frame shaped like the underside of the bridge, was constructed over the river. The stones where then set on the frame, without mortar. The bridge was filled in with rubble and dirt, which over time would compress against the abutments. The wooden frame was then removed. If constructed correctly a stone-arch bridge should last indefinitely, the Sands Bridge is not a well built bridge. Photographic evidence shows the keystone had slipped by the late nineteenth century. The bridge was used consistently until it was taken out of service in 1963 when the Spicket River was rerouted and Interstate 93 was built.

Current status
As of May 2009, the bridge is in a terrible state of disrepair and is in danger of collapse. However, Methuen city officials want to make the area more accessible to the public and have unveiled plans to restore the bridge and build an adjoining park with walking paths, viewing areas, "rustic seating" and a parking lot. It was added to the National Register of Historic Places June 20, 1984
