Karmsundet

Karmsundet is a strait located in Rogaland county, Norway. The long strait separates the island of Karmøy on the west and the mainland of Norway and island of Vestre Bokn in the east. The strait runs through Haugesund Municipality, Karmøy Municipality, and Bokn Municipality. The town of Haugesund lies at the northern end of the strait and the town of Kopervik lies in the central part of the strait, and the town of Skudeneshavn lies near the southern end where the strait flows into the Boknafjorden. The Karmsund Bridge, a part of the European route E134 highway, links Karmøy island to the mainland. The bridge was completed in 1955. The small islands of Vibrandsøya, Risøya, and Hasseløya lie in the strait at the northern end, just off shore from the town of Haugesund.

Near the Norsk Hydro Factory on Karmøy island, there are three powerlines that cross the Karmsundet on tall electricity pylons, which are the tallest in Norway. A local newspaper in this area is named after the strait: Karmsund Avis.
