Heavier cables mean bigger anchorages. The new bridge had a much bigger cable load, increased from the original 28 million pounds to 36 million pounds. As a result the anchorages of the 1940 bridge needed to be modified. The old anchorages, spaced 39 feet apart, were retrofitted for the new span's 60-foot spacing between cables. The original structures became the cores of the new, heavier and wider 54,000-ton anchor blocks.
