Do you live near the E4 and are being disrupted by loud explosions? Don't worry, it's probably only the local energy company, Skellefteå Kraft, preparing the ground to install a new overhead power cable between Kvistforsen and Tjärn. The blasting will take place between 07:00 and 20:00 on Mondays, Tuesdays, Wednesdays and Thursdays until week eight, which begins February 20.
