A lattice girder, like any girder, primarily resists bending. The component sections may typically include metal beams, channel and angle sections, with the lacing elements either metal plate strips, or angle sections. The lacing elements are typically attached using either hot rivets or threaded locator bolts.
The use of laced struts within a lattice girder can be seen in the two photographs of the c1860s lattice girder bridge at Llandeilo. The first table lists these early examples. (Note that some bridges, for example the New Clyde Viaduct (or Second Caledonian Bridge) in Glasgow, appear to be of lattice construction whereas in fact the latticing ...
A simple lattice truss will transform the applied loads into a thrust, as the bridge will tend to change length under load. This is resisted by pinning the lattice members to the top and bottom chords, which are more substantial than the lattice members, but which may also be fabricated from relatively small elements rather than large beams.
The bridge is one of twelve double lattice girder bridges that survive substantially intact in the NSW railway system. As such it is of exceptional heritage significance as evidence of a short lived but highly popular approach to bridge design in which the spanning girders were reinforced by a lattice of bars, adjusted to suit changing structural forces.
The bridge consists of four lattice steel spans resting on concrete piers. The total length of the bridge is 1,150 ft (350 m) and 112 ft (34 m) above high water mark. The total cost was over £500,000. [3] The bridge was opened by King Edward VII and Queen Alexandra on 10 July 1906, despite being still unfinished at this time.

The Albury Murray River Bridge is a double-track 4 ft 8 + 1 ⁄ 2 in (1,435 mm) standard gauge, three-span wrought iron lattice underbridge. It is a two span continuous lattice bridge with overhead transverse frames for stabilising the top flanges. The spans are 48 metres (159 ft) to centres of piers and the lattice work has six triangulations ...
