The ferry service between Holmsund and Vaasa is operated by Wasa Line using the M/S Aurora Botnia, with up to two daily departures in each direction taking about three and a half hours.
A road bridge, known as the Kvarken Bridge has been proposed by parties on both sides of the Gulf, along which the E12 could continue without ferry connections. No commitment has been made to build such a fixed link.[1]
