why does the oresund bridge have a tunnel

by Jany Bogisich Published 3 years ago Updated 2 years ago

The justification for the additional expenditure and complexity related to digging a tunnel for part of the way, rather than raising that section of the bridge, was to avoid interfering with air traffic from the nearby Copenhagen Airport, to provide a clear channel for ships in good weather or bad, and to prevent ice floes from blocking the strait.

To accommodate the large shipping traffic through this busy channel, the Øresund Bridge had to be very tall and wide. Additionally, the nearby Copenhagen Airport also required sufficient air clearance for flight traffic. To avoid the fear of an airplane crashing into a support tower of the bridge, the tunnel was built.Mar 7, 2016

The crossing is completed by the 4-kilometre (2.5 mi) Drogden Tunnel fro…

History

Ideas for a fixed link across the Øresund were advanced as early as the first decade of the 20th century. In 1910, proposals were put to the Swedish Parliament for a railway tunnel across the strait, which would have comprised two tunnelled sections linked by a surface road across the island of Saltholm. The concept of a bridge over the Øresund was first formally proposed in 1936 …

Link features

At 7,845 m (4.875 mi), the bridge covers half the distance between Sweden and the Danish island of Amager, the border between the two countries being 5.3 km (3.3 mi) from the Swedish end. The structure has a mass of 82,000 tonnes and supports two railway tracks beneath four road lanes in a horizontal girder extending along the entire length of the bridge. On both approaches to the three cable …

Rail transport

The rail link is operated jointly by the Swedish Transport Administration (Trafikverket) and the Danish railway infrastructure manager Banedanmark.

In 2001, both countries also joined the Schengen area, and since then the abolishment of border controls is primarily regulated by European Union law, more specifically the Schengen acquis.

Costs and benefits

The cost for the Øresund Connection, including motorway and railway connections on land, was DKK 30.1 billion (~€4.0 billion) according to the 2000 year price index, with the cost of the bridge expected in 2003 to be recouped by 2037.
