The Seikan Tunnel in Japan and the Channel Tunnel between the United Kingdom and France are both in excess of 50 km (31 mi). Under construction since 2002 and projected open in late 2016, the Gotthard Base Tunnel (a second rail tunnel, 57 km long), will be the world's longest.
Set to open for commercial service in December, the two-way tunnel can handle up to 260 freight trains and 65 passenger trains per day. Swiss planners have dreamed of such a tunnel for decades, and Gotthard's 17 years of construction don't include the many years spent to scope out suitable paths.
