The Churchill Bridge is a historic bridge carrying Mountain Road over Bicknell Brook, in a rural corner of Buckfield, Maine. It is one of three documented stone lintel bridges in the state. It is a dry laid rubble stone structure which carries the road over the stream at a height of about 14 feet (4.3 m). The total length of the bridge is about 20 feet (6.1 m), and the clear span over the brook is 5 feet (1.5 m). The span is formed by five massive ledge stones laid on rubble abutments about 7 feet (2.1 m) above the stream. Additional rubble is laid above to form the bed of the gravel roadway. The bridge crosses the stream at a slight angle, so its abutments are extended with wingwalls to the northwest and southeast.
