Lužný most

Lužný most (English: Floodplain bridge) is a motorway bridge located on the D4 motorway in the Bratislava Region in Slovakia. It crosses the Danube river at the height of 20 m (66 ft) and with the length of 2,932 m (9,619 ft), it is the longest bridge in the region and second longest in the country after the R2 viaduct on the segment between Kriváň and Mýtna.

The bridge was built as a part of a public-private partnership (PPP) project which included the construction of the D4 (Bratislava bypass) and the R7. The construction of the bridge began in 2018 and was completed and opened on September 26, 2021. It features a 2-lane dual carriageway with each lane being 3.75 m (12.3 ft) wide and 2 shared-use paths separated from the main motorway by noise barriers.

Its main purpose is to reduce traffic on the overloaded Harbour bridge in Bratislava.
