Seminar on ORESUND BRIDGE. The Oresund Bridge is a combined railway and motorway bridge across the Øresund strait between Sweden and Denmark. The concept of a bridge over the Øresund was first formally proposed in 1936 by a consortium of engineering firms who proposed a national motorway network for Denmark. At 7,845 m (25,738 ft), 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 Address: Malmö, Sweden Construction started: 1995 Total length: 7,845 m Opened: 1 July 2000 Height: 204 m

3. INTRODUCTION
This Amazing Bridge Turns Into a Tunnel and
Connects Denmark and Sweden
 A part of the Bridge is above water and it runs nearly
8 km.
The remaining part of the Bridge is a tunnel of 4 km

5. Why such combined structure of
BRIDGE,TUNNEL & AN ARTIFICIAL
ISLAND?The shoreline on the Danish side with the Copenhagen international
airport,Kastrup by the building a bridge with Hightower's would have obstructed air
traffic and could lead to a tragedy.
While building a low bridge would have been safer for air traffic but then it
would have blocked Denmark ships.

6. Solution
 To built an under water tunnel close to the airport and bridge on
other side which would be cheaper solution
 Means……..
A tunnel turn into a bridge in the middle of
the open sea which requires island with
the tunnel could emerge from the water.
There were no island existed so engineers decided
to build one.

7. Three main segments of The Oresund Link
 On the Denmark side, the link begins with a 3,510-meter (2.2-mile)
underwater tunnel.
 The tunnel emerges from the water into a roadway on a 4,055-meter
(2.5-mile) artificial island, Peberholm, which appears as a bright
white shape to the south of the natural island in the scene.
 The cable-supported Oresund Bridge stretches 7,845 meters
(4.9 miles) across the eastern part of the Strait toward Sweden,
making a thin white line across the image.

9. Construction of bridge
 Most of the bridge structures – the
bridge piers and bridge spans – were
built on land and subsequently
towed out to the bridge alignment by
a large floating crane.
 The pylons were cast in situ.

10. LOAD TRANSFER
 It has BEARINGS weighing up to 20t each, capable of
bearing vertical loads up to 96,000 kN in a longitudinal
direction and up to 40,000 kN in transverse direction.
 The design, manufacturing and installation of the bearings
were carried out by the SWISS CIVIL ENGINEERING
firm MAGEBA.

12.  Each tunnel element is 176 metres
long, 49 metres wide,
approximately 9 metres high and
weighs around 57,000 ton.
 The towing of the elements
demanded great skill and
precision.
 in the construction phase a radar
station was established to monitor
shipping and guide vessels
through the work areas thus
avoiding any major accidents.
Immersed Tunnel

13. CONCLUSION
 Has increased employment
throughout the region.
 1.83 million people are
working in region, with over
18000 commuters not
included in this number.
 Around 35 million people
travel this route every year.
 Reduced air pollution by
50% as it replaced ferry
transport.
 Increased circular mobility;
helped to reduce the
shortage of labor in
Denmark and has boosted
the property market in
Sweden.
