In light of the ongoing threat of a sub-glacial eruption in Bárðarbunga, which would lead to massive flooding, the Icelandic Road Administration has decided to redesign a new planned bridge over the river Jökulsá á Fjöllum at Grímsstaðir, Northeast Iceland.
The current one-lane bridge is 67 years old and cannot withstand the weight of the heaviest trucks, visir.is reports.
The Icelandic Road Administration had already designed a new bridge, 230 meters long and half a kilometer upriver from the old bridge. Construction was set to begin this autumn.
The relocation of the bridge even further upriver is now being discussed.
Director of Public Road Administration Hreinn Haraldsson said in an interview with Stöð 2 that work on the redesign had begun in light of the risk of a glacial flood.
“It’s a little further into the channel as well as longer and higher, which is much more likely to withstand a glacial flood, both with more space under the bridge and also easier for the water to flow on either side of it,” Hreinn explained.
