Built in 1862 at 251 feet, reduced in length to 229 in 1971, it is still the longest single span covered bridge of its type in the United States. The arch is visible from the outside as well as the inside. The timbers are cut from Douglas fir and the shingles are made of Sugar Pine. The Bridge is both a State and National Historic Landmark. Call for days and hours.
Special tours are available by arrangement.
