Tangled steel

Steel beams supporting the road surface of a bridge are supposed to be straight.

These twisted beams were positioned at a rest stop just outside of Skaftafell. My curiosity led me to a Wikipedia article titled Glacial lake outburst flood where I saw that this twisted bridge was caused by a jökulhlaup (or glacial burst) in 1996. According to Wikipedia:

"The jökulhlaup reached a flow rate of 50,000 cubic meters per second, and destroyed parts of the Hringvegur (Ring Road or Iceland Road #1). The flood carried ice floes that weighed up to 5000 tons with icebergs between 100-200 tons striking the Gigjukvisl Bridge of the Ring Road".
The power of nature is amazing, isn't it?
