At the Cape of Good Hope, a stone wall below and to the right of the road cut through the ridge formed part of a sharp 200 degree curve that enabled the railway to cross from Las Flores Canyon, beyond the ridge, to Millard Canyon around the cape. At Circular Bridge, on the left, the railway used a bridge to reach the upper regions of the steep Millard Canyon. The bridge was 400 feet long with a diameter of 150 feet, on a 4½% grade, and was 20 feet higher from beginning to end, seeming to run into empty space before returning to the mountainside.
