📋 Tender Overview
After months of meticulously planned preliminary work the second of the two new OBB bridge structures could be hoisted over the Salzach on the Pass Lueg this afternoon. A special crane weighing 670 tons set the new structure down to the millimeter. The OBB has invested 11.5 million euros for a high-quality railway infrastructure in the new bridges and the renewal of an avalanche gallery.Despite a difficult wind situation the bridge renewal of OBB on the Pass Lueg was in the final phase with a spectacular climax in the afternoon. After the old railway bridge was dug and transported on Wednesday today the new and modern steel structure over the Salzach could be lifted to its final site by means of a special crane in millimeter work. The structure of the Salzach bridge is 70 meters long ten meters high and weighs 350 tons. In advance the abutments on which the bridge rests were completely renewed. Already in the previous year the supporting structure for the first of the two railway tracks in this section of the Tauern line was replaced.Success through a strong team and reliable partnersThe exact implementation of the approximately two-year construction project was ensured by the good cooperation of the contracting construction companies with the OBB project manager Christian Hss The construction was a challenge solely due to the space available in the gorge and was perfectly implemented by a strong team and reliable partners. OBB-Infrastruktur AG is investing in state-of-the-art and high-quality rail infrastructure so that passengers in Salzburg can continue to travel safely and punctually. In 2019 77 million euros will be earmarked for attractive rail travel all over the state - by 2023 it will even be around 507 million Euro. For the renewal of the two bridges and the adjoining avalanche gallery the BB is investing around 11.5 million euros.Millimeter and minute accurate workThe new bridge structure was assembled 300 meters from the final bridge site due to the space available in the gorge. Prior to working with the 670-tonne crane the truss structure made of steel had to be driven by a special transporter over the B159 to the bridge construction site. Even the space for the impressive crawler crane had to be prepared in the previous year - the foundation had to withstand a total weight of over 1000 tons in the lifting operations. Already in the previous year the first of the two bridge structures was successfully replaced via the Salzach. Even then the work was completed to the millimeter and so as not to affect the ongoing operation of the railway on the siding to the minute.Elaborate track laying on the bridgeThe first train will be able to drive over the new bridge at the end of November after a load test. Before that the new track systems will be relocated. Another but now familiar challenge for the BB experts due to the conditions on the bridge the track is in a slight curve. All sleepers must therefore be specially adapted and the rails are laid with much effort and partly by hand. The construction work in this section will be used by BB for another project. During the bridge construction work refurbishment work will take place in the adjacent Ofenauer Tunnel until the end of November.
