The ecoduct, built by Skanska, is the first and longest of the four planned ecoducts on the upgraded D1, which has been serving its purpose since September 2021, i.e. allowing the passage of wildlife from one side of the motorway to the other and preventing collisions with vehicles on the motorway. The tube of the ecoduct consists of 25 concrete arches weighing up to 48 tonnes and ten wing segments. The assembly was carried out with the help of a 500-ton crane from Hanyš company and was completed in just 5 days. The ecoduct was covered with a total volume of over 32,000 m³ of soil, railings were built, and landscaping was carried out - humusing, seeding, planting of shrubs and placement of larger stone blocks. In the middle of the ecoduct, a strip of sand has been created so that it will not be overgrown with vegetation in the future and will allow monitoring of animal movements by photo traps placed in the centre of the ecoduct.
