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.
