On the whole, the Swedish Transport Administration described the situation as normal, but traffic leaving the major Midsummer celebrations was gridlocked at times.
According to public radio broadcaster Sveriges Radio's traffic news desk, traffic was brought to a complete standstill on the bridge from the island Öland, with queues of several kilometres.
Five people were reported to have been killed in various accidents over the weekend.
The first fatal crash occurred on Midsummer Eve on Route 40, outside Borås. A couple in their 80s attempted to drive through a gap in the central barrier to change direction, when they were hit from behind by another car. The couple later died on the way to hospital.
Just after 3am on Midsummer's Day, a motorcyclist went off the road outside Länna in Stockholm. The motorcyclist was taken to hospital with life-threatening injuries and passed away later that night.
On Sunday afternoon, two men aged around 20 were killed in a single-vehicle accident in Kalix, northern Sweden, according to police. Regional newspaper NSD reported that the car had veered off the road.
