The following table of particulars of some of the bridges of this
class, from designs of Messrs. Kennard, which have been manu-
factured by them at the Viaduct Works, may be found useful for
reference in forming approximate estimates of the cost, in England,
of iron superstructure of bridges of the kind illustrated; amongst
these may be mentioned one which is noted (a) in the margin, it
being remarkable as having been made in an exceedingly short space
of time. The order was received at Crumlin Viaduct Works on
12th July, and the bridge was designed, made, and on its way to
the shipping port on the 1st August, that is to say, in eighteen
working days. It is about 230 feet long, and the weight, including
piers, is about 300 tons; it contains 2500 bars and plates, 530 cast-
ings, 30,000 rivets, 8500 bolts, &c.
