Since the Second Tay Bridge's completion, the lattice girder arrangement has become a commonplace feature, near-universally adopted for bridge construction. The configuration provides for a high levels of compression strain despite the girders being comparatively light. The decking is composed of steel and is surrounded both sides of the bridge by a closely knit latticework, which functions as a wind screen as well as somewhat protecting the workers. On 9 March 1882, the work on the second
