The stable sub-foundations are of high bearing-quality on solid strata. At the Brooklyn tower, 1860s borings established gneiss at elevation -97 feet, topped by 45 feet of solid-enough strata on which to establish the tower foundation (bottom of the caisson). On the New York side, the concrete-filled caisson rests on hard materials over bedrock enc...
Above the deck rise the buttressed double-arches. The buttresses are additive elements to the three-shafts-with-pointed-arch tower structure. The towers ascend to a reentrant spandrel, water table, and entablature under the summits of 316 feet (Brooklyn) and 350 feet (New York). The New York tower is slightly larger than the Brooklyn tower. The tow...
Theoretical engineering analysis was far from understood in the 19th century. Engineers at the time continued to strongly favor testing by loading, rather than by the emerging elastic limit calculations which were considered by most, if not all, contemporary engineers to be unreliable “complications.” Graduating from Berlin’s Royal Polytechnic Scho...
Rail tracks conveyed bridge components to sites from the waterfront. To build the arches, stone beds for the saddles, and tower tops, steam-powered hoists raised granite stones weighing nine tons or more, each, by way of lewising each stone. Each stone would have 4½-inch-deep mortises drilled into it, into which the counterpart tenon in the lewis d...
Arcades of arched construction, with exterior faces of rusticated stonework trimmed with voussoirs of contrasting stone, run longitudinally under the floor of the long approaches landside of both anchorages. Here, John Roebling devised income-producing interior spaces intended for housing, shops, or offices within the arch blocks. Today, mostly vac...
The original approach-decking used in the superstructure – the nation’s second use of rolled structural steel sections in a bridge superstructure, according to HAER (Historic American Engineering Record) – was recently replaced with pre-cast, concrete-filled steel grid panels. Some approach under-deck arch block exterior walls are undergoing reinfo...

Jul 17, 2023 · The cable strands are bolted into rod-iron eye-bar chains encased inside the masonry of the anchorage and then an anchor plate holds the end of each chain in place.
From both anchorage bases of about 129 x 119 feet, there is a straight batter of ½-inch per foot rise over about 85 feet elevation to 114 x 117 feet at the top. John Roebling used his 1846 patent for Rows of Anchoring Suspension Chains to Cables, invented for the Cincinnati Bridge over the Ohio River and enlarged for the Brooklyn Bridge.
