Significant rainfall is expected over the next 24 hours around the Eyjafjallajökull glacier in South Iceland and may cause considerable flooding on the Jökulsá river. The Road and Coastal Administration will be monitoring conditions along the Ring Road and bridges in the vicinity, but it is uncertain whether the temporary bridge crossing the Jökulsá river where it runs through the Sólheimasandur flood plain will withstand rising waters. This per an announcement made by the Road and Coastal Administration on Tuesday night.
Construction is currently underway on a new bridge over the Jökulsá at Sólheimasandur and in the meantime, traffic is being diverted onto a temporary bridge. The administration is currently hard at work deepening the riverbed and making other preparations that will hopefully prevent major flooding. Nevertheless, the temporary bridge may not survive significant water rising. In the event that the temporary bridge becomes impassable, traffic east of Skógar will be redirected onto the new bridge and a system of alternating green lights will allow traffic to travel in both directions.
The Road and Coastal Administration notes that railing has not yet been finished along the new bridge so if it is necessary for travellers to use it, the speed limit will be temporarily reduced as a safety precaution. Drivers are asked to heed any such speed reductions.
The Met Office has issued a yellow warning for South Iceland and expects heavy rainfall in the entire region, but especially around Eyjafjallajökull and Mýrdalsjökull glaciers. Travellers whose journeys are expected to take them over unbridged rivers are advised to reconsider their travel plans at this time as these rivers may be very difficult to cross or completely impassable.
