Both fatal accidents occurred in Västerbotten.
One accident occurred on Thursday morning when a motorcycle collided with a truck on the E4 in Skellefteå municipality, the other on road 364 south of Botsmark, writes Västerbottens-Kuriren.
On Thursday, queues were also formed on the E4 between Salem and Södertälje in a southerly direction, according to the Swedish Transport Administration.
Here the traffic moved slowly forward.
Several accidents led to a major impact on traffic, including an accident on the E4 in Helsingborg and one on the E45 at Sunne, writes Aftonbladet.
Even on the E6 in the Tingstad tunnel in Gothenburg, it has been difficult to pass during the day.
- One of the tunnel pipes is closed due to maintenance work.
It is absolutely rolling but it is slow, said the Swedish Transport Administration's press manager Bengt Olsson earlier on Thursday.
Before Thursday, the Swedish Transport Administration expected that the roads would be busiest between 3 pm and 5 pm. But there are still many cars out on the roads even during Midsummer's Eve.
