After the <a href=\"https:\/\/www.tunnelsicherheit.at\/en\/peljesac-every-big-bridge-is-followed-by-a-tunnel\/\">Peljesac Adriatic Bridge-Tunnel project<\/a>, JES is now involved in another superlative project. In Linz, the capital of Upper Austria, a gigantic suspension bridge is currently being built on the Danube, connecting two tunnel portals on the banks of the Danube.<\/strong><\/p>\n<p>The structure will form a western bypass of the city and is expected to relieve the Linz city center of 20,000 cars a day. The central component of the project is a 300m long and 22.5m wide suspension bridge &#8220;floating&#8221; above the Danube. Without any supporting pillars, this bridge is directly fixed with over 100 rock anchors in the steep rock faces of the Danube bank. 4 km of the 4.7 km long section are tunneled underneath in an environmentally friendly way. The measurement technology for tunnel safety is again provided by JES from Hallein.<\/p>\n<p>The bridge in figures:<\/p>\n<ul>\n<li><em>The two main supporting cables are each 500 meters long and weigh around 900 tons.<\/em><\/li>\n<li><em>Each of these two main suspension cables consists of 12 individual cables with a diameter of just under 15 cm and a weight of around 75 tons.<\/em><\/li>\n<li><em>These 12 individual ropes &#8211; as a rope package &#8211; measure approx. 1,9 x 0,4 m at the end.<br \/>\n<\/em><\/li>\n<li><em>Total weight of the bridge: approx. 13,000 tons<\/em><\/li>\n<li><em>100 rock anchors with a length of up to 70 meters hold the bridge at both ends at the so-called &#8216;anchor blocks&#8217;.<\/em><\/li>\n<\/ul>\n<p>In addition to the gigantic project volume totaling 745 million euros, the time required for construction and commissioning also means that the bridge will take a long time to complete. The bridge design that has now been realized was found in a competition back in 2003. The actual start of construction dates back to October 2015, the overall project will be implemented in a total of 3 construction phases and the finalization with connection to all incoming and outgoing traffic routes will not be completed until 2031. Completion of construction stage 1 with commissioning of the suspension bridge will take place as early as October 2024.<\/p>\n<p>JES is taking the foreseeable completion of the bridge as an opportunity to hold this year&#8217;s Tunnel Symposium in Linz and to visit the construction site of the bridge and the tunnels together with ASFINAG Bau-Management GmbH (BMG).<\/p>\n<p>An exciting excursion in the context of exciting lectures at the conference hotel <a href=\"https:\/\/nike.arcotel.com\/de\/?r=3771181&#038;gclid=CjwKCAjwq-WgBhBMEiwAzKSH6AQljwoJNiB016BAZ8T-fIdJ1RE-vjmOhWe6E2IWyYECOu9bh2Q3FRoCz34QAvD_BwE\">ARCOTEL<\/a> with a view of the Danube and the city of Linz.<\/p>\n<p>Those who already want more details about the A26 bridge\/tunnel project in Linz can visit the <a href=\"https:\/\/www.asfinag.at\/bauen-erhalten\/bauprojekte\/a-26-linzer-autobahn-knoten-linz-hummelhof-a-7-anschlussstelle-donau-nord\/\">ASFINAG website<\/a> and the <a href=\"https:\/\/blog.asfinag.at\/hinter-den-kulissen\/a-26-donaubruecke\/\">ASFINAG blog<\/a> with animated tunnel and bridge tours, real-time webcam and many more facts and figures about the project.<\/p>\n<p>This year&#8217;s tunnel symposium as well as the duration of the project will always give us cause for further reports.<\/p>\n<p>See you in Linz!<\/p>\n<\/div><\/section><br \/>\n<div  class='avia-button-wrap avia-button-center  avia-builder-el-5  el_after_av_textblock  el_before_av_textblock '>\n<style type=\"text\/css\" data-created_by=\"avia_inline_auto\" id=\"style-css-av-lfjxg34i-2f63bca052b366f1181b300582d1f4b0\">\n#top #wrap_all .avia-button.av-lfjxg34i-2f63bca052b366f1181b300582d1f4b0:hover{\ncolor:white;\ntransition:all 0.4s ease-in-out;\n}\n#top #wrap_all .avia-button.av-lfjxg34i-2f63bca052b366f1181b300582d1f4b0:hover .avia-svg-icon svg:first-child{\nfill:white;\nstroke:white;\n}\n<\/style>\n<a href='https:\/\/www.tunnelsicherheit.at\/4-jes-tunnelsymposium-anmeldung\/' class='avia-color-theme-color avia-font-color-theme-color avia-button avia-button-fullwidth av-lfjxg34i-2f63bca052b366f1181b300582d1f4b0 avia-icon_select-no avia-color-theme-color'   aria-label=\"Registrations for JES Tunnelsymposium here!
