Many people live in Suðurland — Selfoss, Hveragerði, Þorlákshöfn, Hvolsvöllur — and work in or near Reykjavík. The towns at each end can look perfectly calm while the road between them is the problem, because the mountain roads sit far higher than either town.
- Hellisheiði is the main route on Route 1 between Hveragerði and the capital area. It is high, exposed, and closes in winter storms.
- Þrengsli (Route 39) is the lower alternative towards Þorlákshöfn and Route 1. Sometimes one is open when the other is closed — sometimes neither is.
- Both appear separately on the umferdin.is map, with their own status and their own wind measurements.
- Check before you leave in the morning, and check again before you drive home. A road that was open at eight can be closed at four.
If the road closes while you are on the far side of it, you wait. That is the normal outcome here, not a failure. It is worth agreeing in advance with your employer, your partner and your child's school what happens on a day like that.
