I do not have all the details on the health and safety issues, but it is mainly a matter of shoring up components. From time to time, more visual issues may be involved, but there are always components that have to be reinforced to ensure that all health and safety aspects are covered. This covers all bridge maintenance activities. Checks are done. When we find unsound components, we make sure they are repaired before they become dangerous.
