[1] The Chamberlin Mill Covered Bridge is located in a rural-residential area of south-central Lyndon, carrying Chamberlain Bridge Road, a north-south connector between York Street and South Wheelock Road west of United States Route 5.

[4] It is covered by a metal gabled roof with very long eaves, and rests on stone abutments.

Vertical boarding is applied to the lower third of its sides, and also to the portal ends.

The portals project beyond the trusses, and their sheathing is flared at sides to reach the eaves.

It was mentioned in a newspaper in 1881, at which time discussion was ongoing whether or not to cover it, suggesting it was originally built without a roof.
