Even the most basic bridges are engineering challenges exposed to the elements (wind, rain, seawater...) that damage these massive constructions. Intensive road traffic is also a factor of additional constraints. A crack, even a microscopic one, or a rust point in the wrong place can have serious consequences. To avoid the worst, bridges are subject to permanent controls and repairs using advanced techniques such as, for example, breaking concrete with high pressure water or cutting a cable so tight that it could unleash like a giant whip. Maintenance specialists perform daily tasks that are not well known to the public in order to prevent tragedies.
