The <span style=\"font-weight: bold\">Kawazu-Nanadaru Loop Bridge in Japan<\/span> is one such example: How do you build a bridge from one mountainside to another when the sides of the mountain are so steep that it is not possible to build a road at the same elevation on both sides? This double spiral brings cars up and down a full 45 meters (148 feet) while being seemingly suspended in a valley between two mountainsides.<\/p>\n<p><a href=\"http:\/\/imagesh.net\/gallery\/image.php?id=5021\" onblur=\"try {parent.deselectBloggerImageGracefully();} catch(e) {}\"><img decoding=\"async\" src=\"http:\/\/imagesh.net\/gallery\/image.php?id=5021\" style=\"margin: 0pt 10px 10px 0pt; float: left; cursor: pointer; width: 320px\" border=\"0\" \/><\/a><\/p>\n<p>Some other stats:<br \/>\n&#8211; 1.1 km long<br \/>\n&#8211; 80 meters in diameter<br \/>\n&#8211; speed limit: 30 km\/h<\/p>\n<p>Coming upon this bridge in the middle of this mountain road is quite an experience. The bridge was finished in 1982 and has become a popular landmark on route 414 heading south from Tokyo towards the hot spring resorts of the Izu peninsula.<\/p>\n<p>The only way                           for traffic to get down the mountainside into the valley, too steep for any other usual road-building solutions.<\/p>\n<p>The busy Route 414 serves the weekend crowd from Tokyo, intent to wind down at the hot springs resort of the Izu Peninsula. The &#8220;winding down&#8221; bit obviously starts at                           this bridge. The double-spiral structure  demands careful driving &#8211; the speed limit on the bridge    is only 30 km\/h, which also helps to better enjoy.<\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/www.baraskit.se\/random\/img\/82\/spiral_bridge\/1.jpg\" height=\"343\" width=\"463\" \/><br \/>\n<!--more--><br \/>\n<img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/www.baraskit.se\/random\/img\/82\/spiral_bridge\/2.jpg\" height=\"343\" width=\"463\" \/><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/www.baraskit.se\/random\/img\/82\/spiral_bridge\/3.jpg\" height=\"347\" width=\"463\" \/><\/p>\n<p><img decoding=\"async\" loading=\"lazy\" src=\"http:\/\/www.baraskit.se\/random\/img\/82\/spiral_bridge\/4.jpg\" height=\"347\" width=\"463\" \/><\/p>\n<p>I wonder how many people have accidentally driven of the edge due to dizziness.
