THE BLAAUW KRANTZ VIADUCT IN CAPE COLONY.


This viaduct is built over a rocky ravine on the railway from Port Alfred
to Grahamstown, at a height of about 200 ft. from the bottom. Its length
is 480 ft. 6 in., and the width of the platform is 15 ft., the gauge of
the railway being 3 ft. 6 in. The central span of the viaduct is an arch
of 220 ft. span between abutments, and about 90 ft. height; the remainder
of the space on each side is divided into two spans by an iron pier at a
distance of 68 ft. from the retaining wall. These piers are 36 ft. 2 in.
high, and carry girders 144 ft. long, balanced each on a pivot in the
center. One end of these girders is secured to the retaining walls by
means of horizontal and vertical anchorages, while the other end rests in
a sliding bearing on the top flange of the arch.
