Description 

This bridge is one of two similarly designed high-level bridges in Plaistow, the other being on Route 125. Although neither bridge is of an unusual structural design (both are steel stringers), the bridges are both locally noteworthy for their height and the way they suddenly elevate and then drop down on the roadway.

The NH-121 Bridge crosses both the Little River and a set of railroad tracks. One of the tracks is a mostly abandoned Pan Am & CSX Freight Line, and sometimes you can see old railroad cars stored on the tracks under this bridge. The other track is actively in use for the AMTRAK Downeaster. There is also a nearby concrete arch bridge/culvert that just crosses the Little River, serving as an access road to a nearby business.
