Excerpt from The Municipal Engineers of the City of New York: Proceedings for 1910 The proposed Henry Hudson Memorial Bridge, as I presume every member of the Society knows, is designed largely as a rein forced concrete structure, but that does not mean that all parts of the bridge over the 3 000 ft. Of its length are of reinforced con crete. The principal reinforced concrete feature is the main arch over the Spuyten Duyvil Creek, having a clear Span of 703 ft. And a clear height under the sofiit at the crown Of about 180 ft. The approaches are interesting constructions of masonry, but they involve no features of special interest. The spans are circular arches about 108 ft. In the clear. They will be constructed of native stone, i. E., selected gneiss rock as it is found on Manhattan Island.
