Monoliths on
the rise, July 1962.
Bettye Mohney Collection (S-86-124-38:7)
A number of problems had to be overcome at the dam site. To transport heavy Portland cement to the mixing plant, a temporary bridge across the White River and a road to the high bluff were built.
To make best use of the quarry atop the bluff, the concrete mixing plant was placed on a ledge halfway down the bluff face. The height of the plant determined the height of the trestle and the whirley cranes. But the cranes couldn’t reach the part of the dam next to the bluff, so a stationary stiff-leg derrick was mounted on the dam.
Because the first monoliths were constructed opposite the bluff, the entire trestle had to be completed to move the concrete from the mixing plant to the worksite. This meant that some of the trestle footings had to stand in the flowing river. Holes were drilled into the bedrock and reinforced concrete footings installed.
