The alarm was received by SOS at 07 in the morning and three cars are said to be involved.
"There is one car that has driven into the railing and then two have driven into each other. They haven't been so attentive and then that's what happened, says Jörgen Eriksson, officer in charge of the emergency services.
The accident occurred in the lane towards Alnö.
"There is limited accessibility there now. So the traffic is released alternately, says Jörgen Eriksson.
There should not have been any major injuries and police are on their way to the scene.
"We'll be there for about another 15-20 minutes, and it's supposed to be waiting for tow trucks," says Jörgen Eriksson.
