This is a highly unusual truss bridge over the Turner Falls Power Canal, which is seemingly fitting as this power canal is also home to several unique pedestrian truss bridges as well as the triple barreled 11th street bridge. At first glance one might think that the central pier on this bridge has failed as this bridge is not 'straight', so to speak. The northern span is level between abutment and pier, however the southern span has a significantly higher abutment, and thus slops downward to the pier, creating a unusual and unique appearance.

Also of note is the high, but not complete, use of bolted connections for this bridge. Rivets are still used in parts of the superstructure, such as the connections for the built up members, however the gusset plates and many parts of the upper chord employ bolts, which represents an unusual mixture. Whether this was the way the structure was built or if the original riveted connections were replaced during a rehabilitation are unknown.

And another interesting note would be the end post in the Northwest quadrant. It has an additional joint with bracing (indicating that it was indeed part of the original plan and not a later modification). As to why such an unusual design choice was made though would be mere speculation.
