The Øresund Bridge is a combined twin-track railway and dual carriageway bridge-tunnel across the Øresund strait between Sweden and Denmark.


The bridge runs nearly 8 km (5 miles) from the Swedish coast to the artificial island of Peberholm, which lies in the middle of the strait. The remainder of the link is by tunnel from Peberholm to the Danish island of Amager. The Øresund Bridge is the longest combined road and rail bridge in Europe, and connects two major metropolitan areas: those of the Danish capital city Copenhagen and the major Swedish city Malmö. Furthermore, the Øresund Bridge connects the road and rail networks of Scandinavia with those of Central and Western Europe.

The justification for the additional expenditure and complexity related to digging a tunnel for part of the way – rather than simply raising that section of the bridge – was to avoid interfering with air traffic from the nearby Copenhagen International Airport, and also to provide a clear channel for ships in good weather or bad, and to prevent ice floes from blocking the strait. The Oresund Bridge crosses the border between Denmark and Sweden, but in accordance with the Schengen Agreement and the Nordic Passport Union, there are usually no passport inspections. There are random customs checks at the entrance toll booths for entering Sweden, but not for entering Denmark.
