Triad and Day Mountain Bridge
The late bridge, possibly the only one the park paid for.
The park's structure list dates it 1941, after Rockefeller's program ended. Friends of Acadia counts sixteen Rockefeller bridges and one funded by the National Park Service; this may be the one, though that is not confirmed.
