The Challenges of Bridge Maintenance | Engineering Documentary
World’s Most Extreme Bridges: https://youtu.be/g0WSPkdf1OE
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 non-standard 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.
