According to this article the Norwegians are planning on building the worlds first ship tunnel. I'm curious how a ship tunnel differs from a canal tunnel. I don't thinks the size matters since the Rove Tunnel is longer than the proposed Norwegian tunnel and nearly as wide. A friend argued that a ship tunnel is connected to the Ocean and consequently subject to tides whatnot. I don't find this persuasive since the Rove tunnel connects to the Mediterranean. What is the difference between a ship tunnel and canal tunnel that allows to claim they are making the first ship tunnel?
