Bridge and Vatnajökull Glacier

The bridge is built over the river which starts as the runoff water from the melting glacier. We've seen a video of a volcano erupting below the glacier, which caused the ice to melt and produce so much water, that the bridge was destroyed. This one must have at least 1km in length and looks solid enough - when you see that and then watch the video, you can understand the sheer power of the water!
