"The construction of inlet, outlet, and siphon, apart from rather complicated formwork, presented little that was in any way unusual. As they could be used but once, the forms were built up on the spot and wrecked when the concrete had set."

"During construction of the aqueduct temporary bulkheads were built at several points and the shell filled with water for testing. The object was principally to test the efficiency of expansion joints, and no attempt was made to measure deflections. They must have been very small, however, as the leakage under the bulkheads was almost negligible."
