The lenticular truss bridge in Highgate Falls, VT.
This two-span wrought iron lenticular truss bridge was constructed in 1887 by the Berlin Iron Bridge Company in Highgate Center. It currently serves pedestrians. A bit about lenticular truss bridges (and other metal truss bridges here):
Lenticular trusses consist of both upper and lower curved chords, giving the bridge the shape of a lens (hence the name lenticular). This bridge type gained popularity during the early 1880s, and a number were constructed in Vermont.

This is my favorite VT bridge! Beautiful!

My letter to the Concord Monitor uses the Highgate Falls Bridge as an example of what the NH’s abandoned Pumpkin Seed Bridge of LIvermore Falls could be. See: http://www.concordmonitor.com/opinion/11318355-95/letter-save-one-heritage-bridge
