Digital twins are dynamic, data-driven virtual models that replicate the behavior and condition of physical assets in real time. Unlike traditional static models, digital twins integrate live sensor data, predictive algorithms, and advanced simulations to mirror the life cycle of infrastructure systems. In civil engineering, this technology offers transformative potential for infrastructure, including bridges and tunnels, by enabling continuous monitoring, predictive maintenance, and performance optimization. Through this virtual–physical connection, engineers can anticipate deterioration, assess structural health, and plan interventions more effectively, reducing risks and extending asset life. To further understanding of the use of digital twin technology, researchers Lucas Bellini Machado, Ruan Richelly Santos, Dianelys Vega Ruiz, Túlio Nogueira Bittencourt, and Marcos Massao Futai performed a literature review that explores the specific life-cycle phases in which digital twins are applied to bridges and tunnels.
Their study “Advancements of Digital Twin Technology for Bridges and Tunnels: A Systematic Literature Review” addresses the growing need for smarter, more resilient infrastructure management in today’s environment of aging assets and increasing operational demands. The paper reviews how digital twins are applied across different life-cycle phases of bridges and tunnels, highlighting key technologies, current development stages, and implementation challenges. Practicing civil engineers can benefit from adopting digital twins through real-time condition assessment, improved safety, cost-efficient maintenance strategies, and enhanced decision-making.

Abstract
Bridges and tunnels are essential transportation infrastructure components, yet they are highly susceptible to deterioration due to natural aging and unexpected factors. As a result, continuous monitoring and proactive maintenance are essential to ensure their safety and functionality. The integration of advanced technological solutions into asset management is becoming increasingly important for companies to stay competitive. Digital twins have emerged as a promising tool to optimize asset performance and enhance decision-making. Consequently, advancing and updating knowledge on this technology is of paramount importance. This paper presents a systematic literature review that explores the current state of digital twin technology in civil infrastructure, with a particular focus on bridges and tunnels. Drawing on data from 89 relevant research papers, it contributes to the field by examining the frequency of digital twin applications across various life-cycle phases, evaluating their specific purposes and uses, identifying the most commonly applied technologies for these critical infrastructures, and assessing the level of development based on the integration of technologies. Additionally, the paper highlights key challenges and provides directions for future research regarding the application of digital twins to bridges and tunnels.
