At 03:30 last night, a truck with a trailer drove into the ditch along the E4 just north of Vagnhärad.
The Swedish Transport Administration states that salvage work is underway and that the road is therefore closed in the direction of Stockholm.
A preliminary forecast for when the road can reopen is set for 9 a.m. In the meantime, traffic is being diverted via route 218, route 800 and route 525.
It is unclear whether the driver was physically injured.
