The long tunnel under the Oslo Fjord that connects Drøbak and Hurum was closed indefinitely this week after a large truck collided head-on with a car on Wednesday. The driver of the car, a woman, was killed instantly.
Police remained unsure of the sequence of events, but said the car collided with the truck’s trailer. It was full of sawdust, which spilled its contents into the underwater tunnel that has a steep decline and rise on both ends.
The tunnel, part of Norway’s State Highway 23, is 7.3 kilometers long and has a history of accidents and closures, often caused because trucks’ brakes catch on fire. Clean-up efforts after Wednesday’s collision took time, police needed to investigate the cause of the crash and then engineers needed to check for any damage to the tunnel walls. It remained unclear when the tunnel would reopen.
