Because of soft foundation material in the bottom of the Grand Coulee, it was necessary to make a 2-mile detour, high over the east side of the coulee. This photo shows some of the heavy basalt rock cutting encountered in the relocated Upper Coulee Highway, commonly referred to as "Million Dollar Mile" on SR-155. – June 1, 1950
