[1] The Middlebury Gorge Concrete Arch Bridge is located in the upland area of eastern Middlebury, carrying Vermont Route 125 across a narrow gorge en route to one of three passes across the Green Mountains in eastern Addison County.

The bridge consists of a basically semicircular arch made out of poured reinforced concrete.

The sides of the bridge are simply decorated, with a beltcourse running along the length of the top, and paneled pilastered pillars at the corners.

The bridge was built out of eight separately poured concrete sections, using locally sourced materials.

Its principal defect is the loss of one of the corner posts.
