Smarter infrastructure: The rise of short-span steel bridges

As global infrastructure demands grow, the construction industry must find ways to build more quickly, sustainably, and cost-effectively. This video explores how short-span steel bridges are addressing these challenges through standardised designs, modular construction methods such as press-brake tub girders (PBTG), and the application of Lifecycle Cost Analysis (LCCA) to evaluate long-term value beyond initial expenditure. These innovations not only enhance cost efficiency and allow for rapid installation—sometimes enabling bridge placement within a single day—but also contribute to a broader shift in perception, as training and education help stakeholders recognise the advantages of steel solutions in delivering smarter, more resilient infrastructure.
