The bypass will consist of 13 basins, reaching a length of nearly 100 meters. The dotation will be 400 l/s, allowing fishes up to 80 cm length to pass it. 

Start of construction work was in March, the project will be finished in June 2016. The costs of nearly 700.000 € are covered by the Republic of Austria.
