Vaðlaheiðargöng is a toll tunnel in the north of Iceland along Route 1, just east of Akureyri. It passes between Eyjafjörður and Fnjóskadalur. It is 7.4 km (4.6 mi) long and replaces a 21 km section of Route 1 including the Víkurskarð pass, often closed during winter. The tunnel shortens the travel between Akureyri and Husavik by 16 km. As of 2024, it is the only toll road in Iceland.
