The Groot Noordhollandsch Kanaal (Great North Holland Canal), now known simply as Noordhollandsch Kanaal, is a canal in the northwest Netherlands. The canal stretches about 75 kilometres, connecting several cities in North Holland: from Den Helder in the north, through Alkmaar and Purmerend, to Amsterdam at its southern end. A unique element of the canal are the floating bridges, so-called vlotbruggen (“raft bridges”).
