The bridge is used by 50,000 vehicles per day and carries six lanes of traffic, U-Bahn tracks, two footpaths, two cyclepaths and two utility tunnels.

A truss of iron girders spanned the main river, with vaulted bridges crossing the flood plains on either side.

The technical plans were drawn up by the architects Siegfried Theiß and Hans Jaksch, with artistic control being given to Clemens Holzmeister.

This suspension bridge, built between 1934 and 1937, carried four lanes of traffic, two tram lines and footpaths on both sides.

The main reason for the collapse was determined to be a structural failure in the bearings, which was not spotted during inspection due to the massive granite mantle that surrounded them.
