They call it the Laerdalstunnelen and it stretches 24.5 kilometres (15.2 miles) on the main route between Oslo and Bergen. <a href=\"https:\/\/en.wikipedia.org\/wiki\/List_of_long_tunnels_by_type#Road\" target=\"_blank\" rel=\"noreferrer noopener\">Other sites<\/a> corroborate the claim so I guess it\u2019s a fair assessment. Fact checking isn&#8217;t my strongest suit. Don&#8217;t take what I say necessarily at face value.<\/p>\n\n\n\n<p>I can\u2019t possibly imagine what it must be like to drive that distance underground and apparently the engineers who designed it couldn&#8217;t either, so they constructed three large &#8220;caves&#8221; along the route to break the monotony.<\/p>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">World&#8217;s Longest Subaqueous Automobile Tunnel<\/h2>\n\n\n\n<figure class=\"wp-block-image size-large\"><a href=\"https:\/\/commons.wikimedia.org\/wiki\/File:Umihotaru_Parking_Area_Aerial_Photo_20150131.jpg\" target=\"_blank\" rel=\"noopener\"><img decoding=\"async\" src=\"https:\/\/upload.wikimedia.org\/wikipedia\/commons\/thumb\/8\/8f\/Umihotaru_Parking_Area_Aerial_Photo_20150131.jpg\/1024px-Umihotaru_Parking_Area_Aerial_Photo_20150131.jpg\" alt=\"Umihotaru Parking Area Aerial Photo 20150131.

You\u2019ll want to head towards the <a href=\"https:\/\/en.wikipedia.org\/wiki\/Tokyo_Bay_Aqua-Line\" target=\"_blank\" rel=\"noreferrer noopener\">Tokyo Bay Aqua-Line<\/a> in Japan. The tunnel portion of this bridge-tunnel combo under Tokyo Bay extends 9.6 km (6 miles). It also offered me the opportunity to use the word &#8220;subaqueous&#8221; which isn\u2019t something one encounters every day. Cool.<\/p>\n\n\n\n<p>Google Street View extends onto this rather unusual platform at the tunnel entrance (<a href=\"https:\/\/goo.gl\/maps\/ZQ2bqgg3ABJ19Jii7\" target=\"_blank\" rel=\"noreferrer noopener\">map<\/a>). It has a bunch of shops, restaurants, and arcades which serves as a destination unto itself. I suppose it\u2019s possible to go to the little man-made island, make an afternoon of it and go home without going through the tunnel. However if I\u2019d just spent <a href=\"https:\/\/www.google.com\/search?hl=en&amp;q=%C2%A53000++to+%24&amp;aq=f&amp;aqi=&amp;aql=&amp;oq=\" target=\"_blank\" rel=\"noreferrer noopener\">\u00a53000<\/a> you better believe I\u2019d go back and forth through that tunnel as many times as they\u2019d let me pass. That\u2019s a serious toll.<\/p>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Longest Railroad Tunnel<\/h2>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"The Gotthard Base Tunnel in Switzerland | Made in Germany\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/UDrHNTB8wW4?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><figcaption>UPDATE: It opened in December 2016<\/figcaption><\/figure>\n\n\n\n<p>I don&#8217;t have an image of what will be the the world&#8217;s longest railroad tunnel because it&#8217;s under construction in Switzerland. When it&#8217;s finished sometime around 2017 or 2018 it will extend an astounding 57 km (35.4 mi). It&#8217;s called the Gotthard Base Tunnel (GBT) and there&#8217;s <a href=\"https:\/\/www.alptransit.ch\/en\/gotthard\/gotthard-base-tunnel\/\" target=\"_blank\" rel=\"noreferrer noopener\">an English version of their official website<\/a> if you want all the details. German, Italian and French are also available. See you in a few years at the grand opening!<\/p>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Longest Canal Tunnel<\/h2>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Film a\u00e9rien du Touage souterrain de Riqueval\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/wCNb_EScEGs?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>Canals were an efficient method of transportation in the Eighteenth and Nineteenth Centuries until the railroads arrived. In many ways they&#8217;re an anachronism, but lots of them them have survived into the modern era for a variety of reasons including nostalgia and tourism.<\/p>\n\n\n\n<p>Sure, canals needed tunnels just like other forms of land-based transportation. The longest canal tunnel still in existence can be found in Riqueval, France. It was built between 1802-1810 and it extends 5.67 km (3.5 mi).<\/p>\n\n\n\n<p>Streetview has lots of great images in the area, but not of the actual canal entrance because the banks of the canal are raised and topped by vegetation. The <a href=\"https:\/\/goo.gl\/maps\/NJHCURuqtZcdMqQJ6\" target=\"_blank\" rel=\"noreferrer noopener\">satellite image<\/a> is pretty good, though. You can follow its path by looking along the surface &#8212; simply follow the narrow line of trees.<\/p>\n\n\n\n<p>It&#8217;s called the &#8220;Touage souterrain de Riqueval.&#8221; Those of you who speak French probably have a great translation for that phrase but the best I figure was something like the &#8220;subterranean tow canal of Riqueval.&#8221; Indeed, a small barge tows other barges along the canal and through the tunnel. <a href=\"https:\/\/fr.wikipedia.org\/wiki\/Souterrain_de_Riqueval\" target=\"_blank\" rel=\"noreferrer noopener\">French Wikipedia covers this site<\/a>, as does the video embedded above. You&#8217;ll really like the video if you enjoy looking at a tunnel from every conceivable angle. I liked it but I&#8217;m not sure what that says about me.<\/p>\n\n\n\n<hr class=\"wp-block-separator\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Longest I&#8217;m Not Sure What to Call It<\/h2>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Whittier Tunnel\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/O6V9mk2SMPo?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" allowfullscreen><\/iframe>\n<\/div><\/figure>\n\n\n\n<p>I couldn&#8217;t find this shared automobile &#8211; train tunnel on the Portage Glacier Highway in Whittier, Alaska on the Worlds Longest Tunnel page. Maybe it&#8217;s there. I don&#8217;t know. Oddly this was the one tunnel that got me interested in the topic and somehow led me to the website. I&#8217;ve had a fixation on this tunnel lately (<a href=\"https:\/\/goo.gl\/maps\/uj81MvJy29DXzw4o6\">map<\/a>).<\/p>\n\n\n\n<p>The Alaska Department of Transportation calls this the Anton Anderson Memorial Tunnel. They describe it as the &#8220;longest combined vehicle-railroad tunnel in North America.&#8221;<\/p>\n\n\n\n<p>It&#8217;s about 4 km (2.5 mi) so it&#8217;s not in the same class as some as the others. The interesting aspect, however, is that it&#8217;s the <em>only<\/em> land connection between Whittier and the outside world. The tunnel has room for a single lane of traffic so vehicles move back-and-forth on an established schedule. In addition there are occasional delays whenever a train needs to use it!<\/p>\n\n\n\n<p><em>UPDATE: I <a href=\"\/blog\/?p=22471\">drove through this tunnel<\/a> in July 2010.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>I\u2019ve been enjoying the World\u2019s Longest Tunnel page recently and I decided to see if I could locate some of the more striking examples using maps and photo sites.
