This view from the Willow Springs Road Bridge looking northeasterly on July 20, 1897, shows the transition of the Main Channel from the vertical wall rectangular Rock Section for contract Section 1 in the foreground to the sloping wall trapezoidal Earth and Rock Section for contract Section A in the background. This transition was necessary because bedrock was no longer prevalent toward Chicago. (MWRD photo, disc 127, image 96)
