Thanks to blasting, the Queensboro Bridge in New York, which was open to public traffic in 1909, is still functioning safely today!
In 2004, a set of complex analyses revealed the fact that rehabilitating the bridge connecting Queens to Manhattan was absolutely necessary, in order for this extremely important access way to keep being used normally.
The bridge’s protective paint layer, exposed to salty air, to intensive traffic and to other corrosive agents, had deteriorated to the point that, in certain areas, the metallic structure was directly exposed to the atmosphere. It was decided that, the best solution in this case was to completely clean the metallic structure by means of blasting.
After executing the blasting operations, the bridge was fully rehabilitated and it is still in use today, serving the inhabitants of New York.
