Maine once had more than one hundred covered bridges. Only seven of these bridges remain today, but the photographic record of the others is surprisingly complete. Maine's Covered Bridges offers views of these structures that once graced the state's roads and railroads, many of them in the Oxford Hills and Western Mountains regions. All of Maine's major rivers-the Saco, Androscoggin, Kennebec, Penobscot, and Aroostook-and even smaller rivers-including the Presumpscot, Ossipee, Little Androscoggin, Ellis, Sandy, Piscataquis, Narraguagus, and St. Croix-had a covered bridge.
