THE CHALLENGE OF BRIDGE MAINTENANCE

Massive constructions under pressure

Synopsis

Even the most basic bridges are engineering challenges exposed to the elements (wind, rain, seawater...) that damage these massive constructions. Heavy road traffic adds another constraint. A crack, even a microscopic one, or a rust spot in the wrong place can have serious consequences.

To avoid the worst, bridges undergo regular inspections and repairs using advanced techniques such as breaking concrete with high-pressure water or cutting a cable so tightly it could snap like a giant whip.

Maintenance specialists perform daily tasks the public rarely sees to prevent tragedies.
