With a total length of 138.40 metres and four spans of 34 metres each, it is specially designed for permanent use under full traffic load.<\/p><p>In future, the bridge will connect Haslach and Fischerbach via the new route of the K5357 motorway, spanning the Kinzig river. Its load-bearing structure consists of five block-bonded glulam beams, which form a high-performance structure in combination with a reinforced in-situ concrete slab. The innovative timber-concrete composite construction method not only enables a high load-bearing capacity, but also scores points for its low use of materials and energy.<\/p><p>Great importance was attached to structural timber protection: Stepped cross-sections and the overhang of the carriageway slab reliably shield the structure from the weather and ensure the longevity of the load-bearing structure. In terms of design, the slender, technically precise structure blends harmoniously into the landscape. V-shaped tapered pillars and finely structured exposed concrete surfaces emphasise the design claim.<\/p><p>Designed in accordance with current standards for traffic loads according to load model 1 as well as for wind and earthquake loads, the structure fulfils the highest technical requirements. A well thought-out bearing concept, maintenance-friendly construction details and durable sealing systems round off the overall concept.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t<div class=\"elementor-element elementor-element-9a9a3de e-con-full ci-right e-flex e-con e-child\" data-id=\"9a9a3de\" data-element_type=\"container\" data-settings=\"{&quot;jet_parallax_layout_list&quot;:[]}\">\n\t\t\t\t<div class=\"elementor-element elementor-element-d26fcdc elementor-widget elementor-widget-text-editor\" data-id=\"d26fcdc\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p><strong>Owner<\/strong><br \/>Landratsamt Ortenaukreis<\/p><p><strong>Year of construction<br \/><\/strong>2025<\/p><p><strong>Dimensions<\/strong><br \/>Length: approx. 140.00 m<br \/>Spans: approx. 34.00 I 34.00 I 34.00 I 34.00 m<br \/>Width: approx. 12.30 m between the railings<\/p><p><strong>Planning<\/strong><br \/>Timber construction: Ingenieurb\u00fcro Miebach<br \/>Foundation, piers and abutments, formwork and reinforcement of superstructure: <a href=\"https:\/\/rs-ingenieure.de\/\" target=\"_blank\" rel=\"noopener\">RS Ingenieure, Achern<\/a><\/p><p>Execution<br \/>General contractor: <a href=\"https:\/\/rendler-bau.de\/\" target=\"_blank\" rel=\"noopener\">Rendler Bau GmbH<\/a>, Offenburg<br \/>Timber construction: <a href=\"https:\/\/www.grossmann-bau.de\/\" target=\"_blank\" rel=\"noopener\">Grossmann Bau GmbH &amp; Co.
