Mitchell's Point

Mitchell's Point is a rock bluff overlooking the Columbia river about 57 miles east of Portland and about 30 miles west of The Dalles. During the construction of the Columbia River Highway in 1915 a tunnel was bored through the point. The tunnel was 400 feet long and 18 feet wide. The walls were 10 feet high with a semicircular roof, having a 9 foot radius. In the tunnel were 5 windows which opened out over the river and gave a view of the river and Washington shore. The windows were elliptical in shape, 20 feet wide and 19 feet high. The western portal of the tunnel was reached over a 230 foot reinforced concrete viaduct.
