Sentinel Pine Bridge

No. 38

Built in 1939 by the Society for the Protection of New Hampshire Forests, the Sentinel Pine Bridge spans the Pemigewasset River at the Flume in Franconia Notch. The 61-foot bridge incorporates a section of the Sentinel Pine, a more than 200-year-old tree that was blown down by the Hurricane of 1938. Local millwright John G. Welch and “Old Joe” Poloquin hand-made the original cedar roof shingles. Steel supports and cables were added in 1970, followed by a modified Bailey Bridge beneath the structure in 1984 to relieve the load on the pine. The roof was replaced by state crews in 2002.
