Description 

It is an example of a lenticular truss, so named because of the lens-like shape of its curved upper and lower chords. It is representative of the Berlin Iron Bridge Company's trademark bridge type, based on the patent of William O. Douglas. This bridge also exhibits a Warren pattern of web bracing and a highly decorated portal. The process of moving the bridge in 1985 is a notable example of how historically significant bridges can be preserved and adapted to new uses. -- Historic American Engineering Record
