Europe’s Longest Road and Railway Bridge

Caitlin Dempsey


The Øresund Bridge, also known as the Øresund Link, is 16-kilometer-long bridge that connects the Danish capital of Copenhagen with the Swedish city of Malmö.

It is a combined railway and automobile bridge-tunnel that spans the Øresund strait, a narrow body of water that separates Denmark and Sweden, connecting the North Sea with the Baltic Sea.

The Øresund Bridge is the longest combined road and railway structure in Europe.

How old is the Øresund Link?

The idea of connecting Denmark and Sweden was first proposed in the early 20th century, but it wasn’t until the 1990s that plans for the Øresund Bridge began to take shape. Construction began in 1995, and the bridge was officially opened on July 1, 2000, by Queen Margrethe II of Denmark and King Carl XVI Gustaf of Sweden.

The Øresund Link has three sections

The Øresund Link is an impressive feat of engineering and is made up of three sections.

Starting on the Denmark side at Copenhagen there is a 3,510-meter (2.2-mile) underwater tunnel. The underground portion of the Øresund Link was designed in order to allow ship traffic to travel through the Øresund Strait. A tunnel was chose in lieu of raising the bridge in order not to interfere with air traffic in the region.

The next segment starts at the artificial island, Peberholm, that sits in the middle of the Øresund strait just south of the natural island, Saltholm, which is part of Denmark. There, a 4,055-meter-long (2.5-mile-long) roadway stretches across Peberholm. Finally, the 7,845 meter-long (4.9 miles) cable-supported Oresund Bridge completes the connection to Malmo, Sweden.

Benefits of the Øresund Link

The Øresund Link has had a significant impact on the region’s economy, making it easier for people to travel between Denmark and Sweden. The bridge has also made it easier for businesses to operate in both countries, facilitating trade and commerce. The bridge has also been a boon to tourism, making it easier for visitors to explore both Copenhagen and Malmö.

By providing an alternative to air and sea travel, the connection has helped to reduce carbon emissions. The bridge has also reduced traffic congestion, particularly in Copenhagen, where it has helped to alleviate some of the city’s traffic problems.

Overall, the Øresund Bridge is an impressive feat of engineering that has had a significant impact on the region’s economy, environment, and transportation and strengthened the close relationship between Denmark and Sweden.
