At the bridge-tunnel crossover point, there is an artificial island called Umihotaru ("sea firefly") with a rest area consisting of restaurants, shops and amusement facilities. Air is supplied to the tunnel by a distinctive tower in the middle of the tunnel, called the Kaze no To ("the tower of wind"), which uses the bay's almost-constant winds as a power source.
