The Hardanger Bridge is a suspension bridge across the Eidfjorden branch of Hardangerfjorden in Hordaland. The bridge connects the municipalities of Ullensvang and Ulvik. It replaced a ferry connection between Bruravik and Brimnes, and thereby shortens the driving time between Oslo and Bergen. It is the longest suspension bridge in Norway.
The bridge is 1,380 metres long, with a main span of 1,310 metres. The maximum deck height is 55 metres and the towers reach 200 metres above sea level. There are two driving lanes for cars with an 80 kilometres per hour (50 mph) speed limit, and a separate lane for pedestrians and cyclists. The deck height means that the largest cruise ships cannot reach the inner Hardangerfjord any more.
The traffic predicted for the bridge was estimated to be 2000 vehicles per day. The opening of the bridge took place on 17 August 2013.
The main span is one of the longest suspension bridge spans in the world. It is also the longest tunnel to tunnel suspension bridge in the world. On the south end of the bridge, cars immediately enter the 1,2 kilometre Bu Tunnel that goes under the village of Bu, while on the north side of the bridge, cars immediately enter the 7,5 kilometre Vallavik Tunnel which includes a 500 metre long segment to a roundabout inside the tunnel. At the roundabout, cars can take another 500 metre long tunnel that leads to Ulvik or they can take a 7 kilometre long tunnel to Granvin.
