This overview represents the current vertical clearance within the marked passage openings of selected bridges on the Austrian Danube.

The published values are based on the corresponding reference water levels of the individual bridges and are updated every 15 minutes. Due to different ways of data transfer slight differences to the bridge clearance published on light signals on bridges and locks may occur.

The published vertical clearance consists of unchecked raw data, which for various reasons (e.g. by systemic disorders) may contain inaccuracies or errors. The consistent publication is not guaranteed. Due to maintenance or defects in the remote transmission equipment values may temporarily be unavailable.

A claim of liability by the publication of the vertical clearance by viadonau, irrespective of the claims and legal basis, is always excluded.
