The tunnel was built as part of a large project including 3 tunnels and a bridge connecting several islands to the mainland.
The bridge–tunnel complex serves the municipalities of Herøy, Sande, Ulstein, Hareid, Ørsta, and Volda, which together have over 40,000 inhabitants.
The Eiksund Bridge joins Hareidlandet island and the village of Eiksund with the nearby island of Eika.
 The Eiksund Tunnel begins at the south end of the bridge (on Eika island) goes under the Vartdalsfjorden and connects to the mainland near the village of Ørsta.

These three structures are a part of Norwegian County Road 653, a highway that links Norwegian County Road 61 between Ulstein and Herøy to the European route E39 highway between Ørsta and Volda.
