Bridges are entering a new digital and AI era. Across the globe, infrastructure owners are beginning to move beyond databases, isolated health-monitoring systems, task planners and static BIM models. The emerging area is a digital twin of the bridge that continuously connects the physical asset with its digital representation, asset administration, operational processes and all related data, creating a live digital environment for managing the bridge throughout its lifecycle. The growing adoption of digital twins in infrastructure reflects a broader shift in how bridge owners and operators approach asset management. Digital twin projects increasingly focus on connecting existing documentation, inspections, sensor and monitoring data, engineering models and other specialist information within a unified digital environment. Rather than serving as a static 3D representation, the digital twin is becoming a platform for continuous asset monitoring, analysis, forecasting and decision support throughout the infrastructure lifecycle.

This point toward a broader change in infrastructure management: The digital twin of the future will not simply show what a bridge looks like. It will help explain how the bridge and its maintenance team have been behaving.
From BIM model to live bridge A conventional digital model answers questions such as:
A live digital twin goes further. It can connect the physical assets to continuously collected information: Bridge - sensors - data – inspections - analytics – maintenance activities - digital model - insight – forecase - action This distinction matters. A BIM model can provide the anatomy of a bridge. Sensor data can provide evidence of its behavior. Analytics can identify changes in that behavior. A live digital twin brings these layers together. Recent research illustrates this shift from visualisation toward interpretation. A 2026 study on large-span bridges describes a digital-twin framework that combines sparse physical measurements with physics-based modelling, data-driven learning and uncertainty-aware inference. Rather than simply displaying sensor values, the framework aims to reconstruct and better understand the structural state of the bridge and forecast/simulate future behaviour for different scenarios. This reflects a broader direction in bridge digital twins: combining monitoring data with models and analytics to provide deeper insight into how infrastructure is behaving.

A Digital Twin Framework for Structural Health Monitoring of Existing Large-Span Bridges
Infrastructure is ageing. Inspection resources are limited. Environmental conditions are changing. Traffic loads evolve. There may be a huge amount of bridge data without a unified understanding of the bridge. Inspection records may exist in one system, BIM data in another, monitoring data in a specialist platform, while photographs, engineering calculations and maintenance information may be stored elsewhere. The challenge is therefore not simply the amount of data, but the fragmentation of information across different systems, formats and stakeholders. A digital twin can provide the integration architecture needed to connect these data sources around the physical structure, creating a more continuous and contextual view of the bridge throughout its lifecycle. This is where digital twins become more than another visualisation tool: they turn fragmented information into a connected operational view of the asset. A bridge digital twin needs context Imagine a vibration sensor reporting an unusual pattern. On its own, the process tells us relatively little.

A live digital twin connects the signal with the physical and operational context. This principle is fully supported by HiPerWare. HiPerWare connects digital representations such as BIM models, 360° photo and diagrams with operational and process data, creating a contextual environment in which data can be associated with the physical anatomy of an asset. The platform also supports high-frequency data collection and AI-based detection of abnormal and inefficient behaviour. For bridge infrastructure, the same principle can be extended from building systems to structural components, monitoring points and infrastructure processes.

A bridge digital twin can be understood as four interconnected layers.
1. The physical layer This is the bridge itself. It includes:
2. The information layer This provides the bridge's digital identity. It can include:
3. The data and analytics layer This is where the twin starts to become operationally useful. It can bring together:
AI-powerd analytics can then identify patterns, deviations and potential anomalies.
4. The decision layer The final purpose is not to collect more data. It is to make better decisions.
This is the point at which digital twins move from monitoring to operational intelligence and forecasting.
Traditional bridge management is heavily dependent on periodic inspections. Digital twins do not eliminate systems inspections. But continuous data can provide another layer of evidence between inspections.Instead of asking only: “What was the condition of this bridge at the last inspection?” asset managers can increasingly ask: “How has the behaviour of this bridge changed since the last inspection?” That difference is significant. A digital twin can establish a historical behavioural context and compare the bridge with itself over time. By continuously connecting structural condition, operating conditions, inspections, maintenance interventions and sensor data, the digital twin can establish a baseline for the individual asset and identify changes in its behaviour throughout its lifecycle. As digital-twin technologies and data standards mature, this capability can be extended further. Where comparable data and appropriate models are available, digital twins can also enable comparison with other bridges or infrastructure assets. This can support benchmarking, identification of unusual patterns and more informed prioritisation of inspections and maintenance activities. For example, a change in vibration characteristics might not automatically mean that damage has occurred. But if the change persists, correlates with another measurement and occurs under comparable operating conditions, it can become a valuable trigger for investigation. The objective should be to collect the right data at the right frequency and with the right contextual relationship. A bridge digital twin does not necessarily need to reproduce every physical variable continuously. Instead, owners need to identify which measurements provide meaningful information about structural behaviour and operational risk. The value of a sensor is not simply the data it produces. Its value comes from what decisions that data can improve. If a measurement can identify an anomaly early, reduce unnecessary inspections, support a maintenance decision or improve understanding, its value can extend far beyond the sensor itself.
The recent tender landscape is particularly interesting because buyers are beginning to describe digital twins in terms of integration and lifecycle management and forecasting, rather than simply 3D visualisation. Its target is a working digital twin of a real bridge, based on a broader IT architecture and connected to information generated throughout the infrastructure lifecycle. Research and demonstration projects are increasingly combining: BIM + sensors + physics + AI + structural-health monitoring + asset management + field maintenace. The bridge digital twin is evolving into an operational information system rather than a standalone 3D model.
This evolution creates an interesting opportunity for platforms that already understand the connection between asset anatomy and live operational data. HiPerWare was developed around this principle in the building environment, combining digital representations with high-frequency data collection, analytics and AI-based anomaly detection to create a live operational view of the asset.
For a bridge digital twin, HiPerWare can be the core Digital Twin platform providing the central environment in which infrastructure data, asset information, and analytical outputs can be natively connected and accessed. It includes the data integration layer, GIS, asset model, sensor integration, dashboards, user management, notifications, diverse visualisation, results repository and reporting. This creates a unified operational environment where information from different systems can be linked to specific bridge components and locations and presented as a live digital twin.
This approach is particularly relevant to complex infrastructure projects because owners do not necessarily need another isolated monitoring dashboard or specialist model. They need a unified operational environment in which information from different systems becomes understandable in the context of the asset itself. The next generation of bridge digital twins will likely become increasingly connected to:
