The St. Louis Bridge had three spans, of 502, 520, and 502
feet. It was designed to carry two levels of traffic; horse-drawn
carriages on the upper level, and a railway on the lower level. This
lithograph drawing of one-half of the center span is from a lavish book
devoted to the St. Louis Bridge, which was written by Calvin M. Woodward
and published in 1881. It provides a good view of the triangular bracing
that connected the steel tubes, as well as the horse and iron-horse
conveyances above. The viewer should be reminded that each span was
supported by four of these arches, spaced at twelve foot intervals;
the flat perspective shows only one arch.
