A desk review of bridge inspection regimes and management systems in six countries was conducted. In all the reviewed countries visual inspections remain the main source of bridge condition data. The literature reviewed revealed that visual inspections as currently practiced are time consuming, costly and subjective. With the increasing backlog of bridge maintenance activities worldwide, technological solutions such as using imaging and thermal sensors mounted on drones, can make bridge inspections more reliable, less time consuming and less costly and as a result provide timely and relevant information for bridge managers. These technological solutions incorporated with bridge information models, may help overcome the subjectivity that human visual inspections are prone to. To utililse the large volumes of sensor data that is generated from these platforms, Level 4 BMS will have to evolve from the current level 3 BMS reviewed in this paper.
Designing Bridges for Inspectability and Maintainability

Bridge Maintenance can be defined as the process of maintaining or preserving a bridge or the process of keeping a bridge in good condition to provide the intended level of service. Thus, the primary purpose of maintenance is to assure public safety by making sure that bridges are in a condition to provide safe and uninterrupted traffic flow. In recent days, the term "Preservation'' is used synonymously with Maintenance. According to the FHWA Bridge Preservation Expert Task Group, bridge preservation is defined as actions or strategies that prevent, delay, or reduce deterioration of bridges or bridge elements, restore the function of existing bridges, keep bridges in good condition, and extend their life. Preservation actions may be preventive or conditiondriven (Bridge 2011). The FHWA Bridge Preservation Guide (Bridge 2011) states that the objective of a good bridge preservation program is to employ cost effective strategies and actions to maximize the useful life of bridges. Applying the appropriate bridge preservation treatments and activities at the appropriate time can extend bridge useful life at a lower

As infrastructure, and bridges in particular age, and environmental concerns and sustainability issues come more and more to the fore, bridge maintenance and management has become a significant challenge. To deal with this problem, Bridge Management Systems (BMS) have been implemented effectively in many countries worldwide (Ireland, US, Switzerland, Denmark etc). In 2008, the IAB- MAS Bridge Management Committee decided to conduct an investigation on the bridge management systems of the world to be issued in conjunction with the 2010 IABMAS conference. This report was based on the completed questionnaires from 18 bridge management systems in 15 countries. The report found that the majority of these systems have only come into place in the last 10 to 20 years (Adey, Klatter et al. 2010) and that of the 18 systems, deterioration is taken into account in 12 of them, although the level of complexity varies widely. The German ‘Bauwerk Management System’ and the Finnish Bridge Management System appear to be among the most technically advanced, with sophisticated deterioration models which allow for age-behaviour models in the Finnish case and particular deterioration models for specific deterioration mechanisms in the German case. Ireland, as yet does not utilize such deterioration models and so consequently this paper outlines the development of a Markovian-based model suitable for predicting structural degradation due to chloride-ion ingress on RC structures on the Irish road network.

Bridges are critical components of transportation infrastructure, connecting communities and facilitating the movement of goods and people. However, the maintenance and rehabilitation of bridges can be complex and costly, especially in the face of increasing traffic demands and changing weather conditions [1,2]. Real-time monitoring of the structural states of bridges can provide reasonable guidance for bridge maintenance, which is helpful to reduce maintenance costs and extend the lifespan of bridges [3–5]. Digital twin, as a promising concept, is widely used for analysis, monitoring, and predictive maintenance of various physical assets, including cities [6,7], factories [8,9], ships [10,11], cranes [12,13], aircrafts [14,15], wind turbines [16,17], and composites [18,19]. Among the substantial research, structural health monitoring is one of the most important applications of digital twins as it can provide real-time reflection of physical assets and facilitate intelligent decision-making based on monitoring. Attracted by the advantages of digital twins in the structural health monitoring, numerous studies have explored the potential of digital twins for bridge infrastructure management [20–29].

Since bridges are communal assets, making decisions regarding their maintenance requires a prudent balancing of several, often competing, decision criteria to fulfill the diverse needs of their stakeholders. But in recent years, issues such as rising traffic volumes, the effects of climate change, a lack of maintenance resources, and deteriorating bridge infrastructure have made it more difficult than ever to come up with the best approach for managing bridge maintenance. To overcome these challenges, solutions derived from multi-criteria decision making (MCDM) techniques have frequently been proposed by several researchers (Chong et al. 2019; Kabir, Sadiq, and Tesfamariam 2014; Patel et al. 2020; Sinha et al. 2009). These techniques provide decision makers with a mathematically sound, auditable, and holistic approach for evaluating a set of alternatives or solutions to select the one that best meets their goals (Bush et al. 2020; Salem et al. 2013).

The number of bridges that have deteriorated beyond their designed safety thresholds continues to increase worldwide. Furthermore, the expenditures that will be necessary to maintain, repair and rehabilitate these bridges greatly exceed the budgetary allocations for these purposes (Goyal, Whelan, & Cavalline, 2017). As daily traffic loads and natural stresses continue to deteriorate the conditions of bridges, proper bridge maintenance has become an increasingly crucial task for bridge-management agencies. Therefore, an updated approach to the management of bridges that optimises the available resources under conditions of uncertainty and of multiple, conflicting objectives is necessary to enhance bridge lifespans (Frangopol, Kong, & Gharaibeh, 2001; Hu, Daganzo, & Madanat, 2015).
