Ayres Natural Bridge


Nature also can illustrate engineering principles, creating natural stone arches as impressive as what the Romans built. And as engineers well know, water can erode some of the hardest substances. The Ayres Natural Bridge, said to be one of only three natural bridges in the world with a stream still flowing beneath it., was created over millions of years. A bend in LaPrele Creek kept gnawing away at a wall of solid rock, eventually shifting course through the newly created opening and forming an arch 30 ft. high and 50 ft. wide. As with man-made arches, the force exerted by the great weight of the stone is transferred to the two sides.
