Interior view of Mainstream tunnel in early 1985 prior to the tunnel being placed in service. The pipeline at right and lighting are temporary for construction. The stairs at left show the entrance to the tunnel of the bottom of a drop shaft, commonly referred to a boot. The stairs are the toe of the boot, whereas, the bottom of the shaft, not in view, is the heel of the boot. The tunnel is lined with concrete throughout. (MWRD photo dated 1985)
