Schengen motorway bridge, International viaduct between Perl, Germany and Schengen, Luxembourg.

The Schengen motorway bridge is a 607-metre-long cantilever bridge over the Moselle, made of two parallel structures with spans of 597 and 607 metres. Its deck rests on pairs of hollow reinforced-concrete piers 1.2 metres in diameter, with a central span of 130 metres and a 4% gradient. The bridge curves with a radius of 1,100 metres and carries two lanes in each direction plus a hard shoulder.

Built from November 1998 to November 2002 as a joint German-Luxembourg project led by Brice Girard, the viaduct cost about 20 million euros and opened to traffic in July 2003. It links the German A8 near Perl with Luxembourg's A13 at Schengen. In 2025 cracks were found in the steel box girders, prompting lane closures and a 44-tonne limit for lorries.

The bridge serves as a daily crossing point where people and goods move freely between two countries without barriers. It represents the reality of borderless travel that many European residents now take for granted.

The bridge experiences heavy traffic during peak hours, particularly in the morning and late afternoon when commuters travel between the countries. Visitors driving across should prepare for typical highway conditions and allow extra time during bad weather.

Because the Moselle is a condominium under joint German-Luxembourg sovereignty, the border signs stand at different points on the two carriageways. The bridge is one of five crossings over the Moselle between the two countries, alongside Schengen, Remich, Wormeldange and Grevenmacher. In 2025 cracks were found in the steel box girders, so one lane per direction was closed from late July 2025 and trucks over 44 tonnes were banned.
