List of tunnels in Iceland

The first tunnel of significant length was opened in 1967 and provided the northern town of Siglufjörður with its first year-round road link to the rest of the country.

All three of these tunnels were built as a single lane with widenings at regular intervals, where vehicles coming from opposite directions can pass.

In 1996 the Vestfjarðagöng tunnel opened in the Westfjords region; it ended the winter isolation of three villages by linking them to the town of Ísafjörður.

In 1998 the sub-sea Hvalfjörður Tunnel opened, reducing the distance from Reykjavík to the town of Akranes by 60 kilometers and consequently abolishing the ferry service between the two.

As per the original plan, the tunnel was turned over to the state on the 30th of September 2018 when the Icelandic Road Administration took over its operation.
