The hydrodemolition robot is a high-pressure water tool that will soon whip several Gordon Highway bridges into shape.



The robot is concrete’s worst nightmare but a dream come true for the Georgia Department of Transportation.



The robot looks like a street cleaner machine on steroids and is expected to begin use Aug. 1 to resurface seven bridges on Gordon Highway from Walton Way to the bridge at the South Carolina state line.



The hydrodemolition robot is still considered relatively new technology, having first been used in 1984. Today, the device is used mostly in the Northeast but its popularity is growing throughout the country.
